- Accidental Innuendo: Aster has a Skill called "The Destroyer of D." The Skill's effects reference Aster defeating Destiny HERO - Plasma (the Ultimate D card) in the anime, but just try explaining that to people taking the name out of context.
- Anti-Climax Boss:
- The Strings Duel in Duelist Chronicles: Battle City Begins was an attempt to re-enact the iconic Slifer the Sky Dragon stand-off, except his deck barely had any way of amassing the 3 Tributes necessary to summon Slifer since he only ran 5 monsters total in a 20 card deck at Level 40. Most Duelists would have to deliberately stall the Duel out in order to see the Egyptian God Card. Another sour note is that there is no FMV for the summoning, like if Rex were to summon Tyrant Dragon.
- Yubel's Level 40 deck has powerful spells and annoying monster effects, but only 1 monster with attacking power, Mystic Tomato. All others, including the various Yubel forms, have 0 attack and defense. When combined with Yubel and Yubel - Terror Incarnate's effects, which destroy her monsters in the end phase, she can easily run out of monsters to hit you with and do no damage as long as you don't attack. Even Yubel - The Ultimate Nightmare's effect is neutered if your monsters aren't on the field, and if she uses a card to bring back Grave Squirmer, it defaults to attack mode and allows you a free hit. Even her Level 50 and 60 decks can be stalled out if you don't set monsters on the field.
- Level 50 Solomon Muto runs a deck focused around gathering Exodia to trigger its Instant-Win Condition, meaning his deck is focused on drawing and searching the pieces. However, a consequence of this is that his deck has no defensive cards and all of his monsters have pathetic stats barring the 2000 DEF Treasure Panda, and he's very prone to bricking and passing his turn without playing anything, making him easy prey for beatdown builds. This makes him overall easier than his Level 40 version, which runs monsters with at least competent stats backed by stat boosts and has Obliterate!!! to repeatedly bounce the player's monsters.
- Good Yosh the Overcrusher (who takes the position of Level 50 Duelist for Mimi's unlock event) runs a Beast Gear deck without the Field Spell
that the Deck needs in order to pose a threat, meaning that his biggest non-Tribute monster is a 1400 ATK vanilla and his ace monster, Catapult Kong
, weighs in at a paltry 2200 ATK with an effect that only works on Defense Position monsters. Unless you brick horribly when he draws into Catapult Kong, it doesn't take very much effort to play a monster that can beat over his entire deck. - Level 50 Nail in Nail's unlock event is designed to largely be a pushover since he serves more as a showcase for Maximum Summoning rather than a legitimate challenge. He starts off with an EX Skill that puts Yggdrago the Sky Emperor on his field in Maximum Mode with the stipulation that it can only deal half battle damage. While 4000 ATK is intimidating and nearly impossible for most decks to get over, you are equipped with your own EX Skill that puts all three pieces of Supreme Machine Magnum Overlord in your hand if you have 4 or more monsters in your Graveyard. If you let Nail run over your monsters for a bit and get your LP down below 1500, you can then proc the EX Skill to get Magnum Overlord, Maximum Summon it, then use both of its effects to boost Magnum Overlord to over 10,000 ATK and OTK Nail instantly.
- Ditto with Asana's event, which similarly assumes that the player does not have consistent access to a Maximum Monster and thus once again supplies the player with the Supreme Machine Magnum Overload EX Skill, making her just as easy to steamroll as Nail. She's actually easier since the Wyrm Excavator she gets does not get the effect that boosts its ATK for each card in her hand, meaning it's stuck at 3500 ATK and thus extremely unlikely to actually kill the player.
- Breather Boss:
- Thanks to the more limited card pool at launch, some of the early Level 40 Legendary Duelists are quite easy:
- Joey runs Fusion monsters with weak materials. His only strong non-tribute monster is Gearfried the Iron Knight, so the mission to win against him 3 times consecutively is far easier than for Mai and Kaiba.
- Téa runs weak Fairy-Type monsters apart from Dunames Dark Witch with equip spells, and her Life Gain strategy doesn't help much when she can easily deck herself out or prevent her monsters from attacking with Cards from the Sky.
- Odion runs weak Zombie monsters with equip spells, with even his Tribute monsters only having 1800 ATK at most.
- Carly Carmine (the regular one, not the Dark Signer) particularly stands out as this. As befitting her anime appearance, she relies entirely on Fortune Fairies which have 0 ATK/DEF and effects that have minimal impact on their own. She's entirely reliant on Miracle Stone (gives 500 ATK/DEF for each Fortune Fairy on the field, maxing out at a mediocre 1500) for any form of offense, and defensively, she only has one copy of Reverse Glasses, which is a worse Mirror Wall.
- Level 40 DSOD Téa runs a Witchcrafter deck with a small Magician Girl engine. While the intent of the deck is to thin until she can summon Dark Magician Girl and buff her with an equip and Kiwi, the result more often is that she can't get a monster on the board higher than 2000 ATK, and is at high risk of decking herself out before she can get her combo off.
- Thanks to the more limited card pool at launch, some of the early Level 40 Legendary Duelists are quite easy:
- Broken Base:
- The first Selection Box was one for some players. One selling point of the box was that it would have cards perfect for newer players just starting to get into the competitive scene and ranked duels quicker. While that's fine if a bit redundant, the sticking issue was that there were also some cards offered in the box not found in any box prior including the valuable Dark World Dealings. Compounding the frustration was that the price per pack was more expensive (though you get more cards in a pack compared to normal) and that it would be taken off the shelves after a set amount of time caused players to claim that the best way to get the cards needed before they were gone is to activate your credit cards.
- Cards introduced in OCG/TCG during and after the ARC-V era: A good chance to use some cards that weren't good enough in that era? Too broken for Duel Links, which doesn't mesh with slower demanding playstyles, such as Cyber Angels and Fur Hires? Or just terrible due to being part of an incomplete archetype?note
- The reveal that a ZEXAL world would be delayed for one based on the Dark Side of Dimensions movie brought a ton of this. Some feel it's a good thing to potentially make the game slow down a bit, while others point out most top decks run modern cards anyway, and Xyz monsters wouldn't do much harm. That's not even getting into people who prefer the season to the movie and vice versa.
- There is also the inclusion of character cards in boxes without the presence of the character that use them. One side is happy that they can play the cards sooner, while the other side feels that it would actively harm contents for future characters, as now important characters don't have many cards left from their respective archetype, that can be used as drops and level-up rewards.note
- Is modern Skill design a good thing for Duel Links? Detractors argue that Skills monopolize deck design to disgusting levels (to the point many decks couldn't even function without them), that their activation has very little counters to be fair (and often contradicts card rulings and effects), that they simplify decks to always performing the same opening salvo, and that only anime decks get to benefit from them. Supporters argue that Skills allow for a more interesting game rather than making Duel Links into a digital version of Speed Duel, that they often support weak decks that never got a chance to shine in the OCG/TCG, that often the real problem with a given deck are the actual cards, and that, if anything, the real problem is that Konami hasn't gone all the way out and gave every single duelist in the game a powerful skill. Pretty much the only thing everyone agrees on is that this design leads to a somewhat scummy practice on Konami's part, which is massively nerfing Skills after a deck has spent enough time on the store, easily turning tier 1 contenders into useless gem/money investments.
- Catharsis Factor: Playing almost any Yu-Gi-Oh! character in a duel against nearly any other character in the franchise leads to some very satisfying matchups.
- Players can use Joey to defeat Kaiba, leaving him in utter disbelief that Joey finally beat him. They can also use Joey to defeat Yami Marik which is very satisfying for fans who felt Joey deserved to defeat him in Battle City.
- Playing as Mai and letting her get revenge on Yami Marik after the fate he subjected her to.
- Playing as Skye and winning against Spectre in his Raid Duel event is immensely satisfying, as their conversation beforehand has a flashback of him brutally beating her and remarking that she's still weak.
- Character Rerailment: Rex Raptor in the Dino Rampage event is simply portrayed as an excitable dinosaur fanboy. He even decides he'll let Joey have Red-Eyes as his signature card (and even before then, he bonded with Joey over being unable to solve the Duel Challenges and Weevil is portrayed as having an interest for him). Notably, since the game primarily follows manga canon, it seems to ignore his Adaptational Villainy in the Doma arc, in which he was vengeful for losing Red-Eyes to Joey and teamed up with Weevil to do his dirty work.
- Complacent Gaming Syndrome:
- The Paradox Brothers' skill Elements Unite allows you to start with the necessary setup to summon the 3750-ATK Gate Guardian on turn 1, at the cost of not having a hand and being reduced to 500 LP. The skill is next to useless in PvP but extremely useful in PVE, allowing the Brothers to easily defeat every opponent without monster removal or effect damage in their decks, as no CPU-controlled opponent has a monster over 3300 ATK without specific equip cards.
- Battle position change cards. With the game format putting emphasis on battle and limited summons in a turn, putting an opponent's monster in defense position can often spell defeat. Cards such as Enemy Controller, Windstorm of Etaqua, and Sphere Kuriboh are highly valued and find their way into top-tier decks thanks to how easily they can turn a game around. Meanwhile, monsters such as Trance the Magic Swordsman or Summoned Skull are looked down upon because of their terrible DEF score which makes them easy prey to these kinds of cards. They've since fallen by the wayside with the release of more actual removal cards and Link Monsters, with the exception of cards like Book of Moon or Floodgate Trap Hole (which put monsters face-down, thus making them unusable for most Extra Deck summons).
- Decks made to farm specific opponents or fulfill specific mission requirements on autoduel are fairly common, such as an Unhappy Girl deck for farming, a Mythical Beast Cerberus deck for high battle damage, or a Téa burn deck for high effect damage.
- During the WCS campaign of 2023, the widespread of Orcust decks became a common complaint, as the pure variant was not only very strong and didn't require any character-specific skills to be played (although Ishizu, Keith and Playmaker were commonly used because of their skills), but its engine was generic enough that the Orcust engine was used in all kinds of different decks, e.g. Odd-Eyes/Pendulum Magician, Onomatopoeia, HERO, Code Talker, etc. Also, during that campaign, Konami asked the players to guess which characters would be most commonly used during that campaign, with the vast majority picking Yuya, Yuto and Yugo because of the immense popularity of Odd-Eyes/Pendulum Magician decks and Speedroid decks at that time.
- Launch Rush Duel essentially boiled down to a race of "whoever draws Multistrike Dragon Dragias
first wins". Dragias is one of the best monsters in the game even in modern Rush, being a 2500 ATK beater that can attack twice if it destroys a monster by battle. It has a great natural statline that is only rivaled by four other monsters, and due to the lack of decent monster removal like Dark Revelation
, once Dragias hits the field it is very difficult to get off. Double attacking is an extraordinarily potent quality in Rush as it is capable of breaking stalemates of your opponent setting three monsters and passing by punching through a defensive line, which can be further accentuated if you manage to get Pierce!
. There's a very good reason why it was released as a Limited 3. - At Rush Duel launch, there were very few decks other than pure Spellcasters that weren't running Summoned Skull. At Level 6 with 2500 ATK, it is a reasonably cheap beatstick that can crash into Multistrike Dragon Dragias, beat over most other ace monsters, and doesn't get checked by Phantom Bind due to the lack of Fiend monsters in the game at release. The only other option for Legend Monster, Dark Magician, is, by comparison, a Level 7 with 2500 ATK whose only realistic use is to be dumped by the Magician's Shuffle Skill to turn all of your Dark Magician Girls into 2500 ATK beaters. Later additions to the card pool have made Summoned Skull less of an auto-include (due to more diverse archetypal Skills and more Legend Monsters to go around).
- In a similar vein, Widespread Ruin was in every Rush Duel deck early in the format; due to the lack of other Legend Traps, pretty much every single deck runs it because there's literally no incentive not to. However, it would quickly be replaced as an auto-include by Negate Attack, which was far better than Widespread Ruin at the role of battle trap due to it blocking all of your opponent's monsters from attacking and dodging destruction immunity. Then Negate Attack got placed on Limited 2 and Widespread Ruin was once again everywhere, due to many stronger decks no longer being able to run Negate Attack without cutting their key cards.
- As for Legend Spells, Tribute to the Doomed is very much the favored option for the slot due to its extremely versatile and powerful removal effect in a format where monster destruction is otherwise scarce. While Shield and Sword can potentially push in more damage, it's more reliant on your other cards and the actual matchup (notably being useless if your opponent happens to pull out a Maximum Monster), while Monster Reincarnation retrieving your cards tends to be less of a premium compared to simply destroying a troublesome boss monster, and The Warrior Returning Alive is only useful in specific decks.
- The very first Goha Rush Festival was utterly plagued by Luke players running pure Dragon decks with his infamous Dragonic Resonance Skill. Dragonic Resonance is an obscenely powerful skill in early DL Rush as it only requires the user to only have Dragon Monsters in their deck and control a face-up EARTH Effect Monster with either 1500 or more ATK or 1300 or more DEF, a pitifully easy statline to hit considering there are a whopping four different cards that meet these conditions and they are all fairly easy to get. Its effect to grant any two monsters with 2300 ATK or less that you control an extra 500 ATK is disgustingly potent for breaking boards as boss monsters top out at 2500 ATK, and it also has the added bonus of boosting the target monsters' Levels by 4, which allows you to dodge conditionals and restrictions that limit what you can do with lower level monsters such as "Sportsdragon Pitcher"/"Sportsdragon Slugger" or "Music Princess's Recital" and easily enabling the effect of Dragonic Slayer
to strip away the opponent's Traps. - After the nerfs to Dragons, the second Goha Rush Festival promptly saw a huge number of Harpie players. Not only were most of the Harpie cards given away for free (Harpie Lady through tickets and events, while the three Harpie Lady Sisters cards were all given out as promo cards for the advent of Maximum Monsters), but they also got a decent Archive Skill to go with them in the form of Hysteric Force, which effectively turns the Harpie Lady Sisters into 2600 ATK beaters that only require a single Tribute. The rest of the deck wasn't too hard to build either due to the very next Mini Box giving more than enough WIND monsters to fill out a deck as well as giving them Harpie's Pet Dragon, a second boss monster that's actually a legitimate threat in Rush Duels, in contrast to its Speed Duel counterpart.
- The Rush Duel meta around the GO RUSH!! world's release was almost entirely composed of Cyber Dragons with a smattering of HEROes, due to Konami being extremely generous with the Structure Decks associated with them - all players got 1 copy of both for free and could get two more with Gems, and both of them got solid Archive Skills, making them extremely cheap to build, easy to pilot, and fairly consistent and powerful.
- Throughout the entirety of the game's history, Kaiba running Blue-Eyes and Yami Yugi running Dark Magician (and to an extent, their DSOD counterparts and normal Yugi) have made up a considerable portion of the PVP meta. By nature of being the mascot characters of the franchise and you starting the game with one of the two, you'll probably invest a fair bit of time building them early on. Blue-Eyes and Dark Magician, being their signature monsters, have a ton of support for their respective archetypes released in many early boosters and structure decks, so it's cheap and easy to put together deck for them. Add in Skills that often let the characters summon their signature monsters without Tribute and/or let them search out cards associated with them (or even play them from outside the deck), and you have a Simple, yet Awesome deck that can take you decently far in PVP. And given that the two are the mascots of the franchise, it's highly unlikely Konami will ever nerf them or slow down releasing new support for them, giving them a degree of futureproofing.
- Jaden running HEROes has also been a fairly common sight for the same reasons as Yugi and Kaiba, as Jaden is the main hero of GX and the first character you unlock in the GX world. HEROes are also by far one of the largest archetypes in the game, giving him no end of new support to add on top of routinely getting new Skills, particularly ones that search Super Polymerization due to it being another iconic card of his.
- One of the most absurdly exaggerated instances of this was the March 2025 GR Festival, which came on the heels of Konami giving every player a full Gaia the Fierce Knight-themed Rush Duel deck along with the extremely powerful Chivalrous Celerity skill for it. Unsurprisingly, the vast majority of decks in the Festival were Gaia decks, to the point where literally every single one of the top 100 decks was using Chivalrous Celerity - including one that didn't even play the Gaia package.
- The WCS campaign of 2025 drew much ire from the playerbase for how intensely limited the meta ended up being. Almost every duelist in Speed format was running Shaddolls, a newly-released and absurdly powerful control deck, or Utopia, whose new Skill gave them the ability to set up half a dozen negates and two 5000 ATK monsters on their first turn. The lower rungs of the competition were also plagued by Jaden running Dragonic Contact, a potent Skill that allowed him to put a 5000 attacker on the board with a negate and Super Polymerization in hand (and, like, Utopia's skill, could be used once per turn). Meanwhile, over in Rush, 75% of the top 100 decks were Light Galaxy, with most of the remaining quarter being its Dark counterpart. The lower rungs had it even worse than Speed, where almost every single deck was Yuga running Master Accel Road, allowing him to easily fuse into multiple powerful Sevens Road monsters. On the bright side, this made it very easy to get the most Gems out of the "Guess which deck will be most popular in WCS" event.
- Crosses the Line Twice: Kaiba and Keith's Jerkass statements when aimed at the little kid NPCs.Kaiba: You're a third-rate duelist with a fourth-rate deck!
Keith: I win! I wish you could see the loser look on your loser face, loser! - Demonic Spiders:
- One thing almost everyone agrees on regarding the Standard Duelist decks is that the level 27 deck Circus Trick is the absolute worst to face, forcing players to run decks specifically built to deal with it. This deck contains Blade Rabbit, Crass Clown, and Dream Clown, which can destroy monsters when their battle positions are changed, backed by a metric buttload of traps that change battle positions, including Windstorm of Etaqua and Labyrinth of Nightmare. End result: every time you try to attack, your monsters get changed to Defense position and then get helplessly destroyed by the opponent's monster effects, until you run out of them and your opponent is free to slowly grind you to death with their weenies. It also makes grinding much more tedious since using Auto-Duel against this deck will result in you getting slaughtered. Thankfully, the release of the ZEXAL world saw Circus Trick being severely nerfed, most notably removing Windstorm of Etaqua and Curse of Anubis and taking away its primary source of annoyance.
- The "It's All Traps" NPC deck, at the same level, is also incredibly annoying due to its use of Trap monsters (especially the Paleozoic archetype, but also including Tiki Soul, makes for a Deck that can very easily Special Summon over, and over, and over, filling the NPC's field and making it very difficult to get an opening to attack). The kicker? It also runs Windstorm of Etaqua, which changes the battle positions of your monsters, which is an OP effect in the Speed Duel format. You practically need to build your Deck with that opponent in mind if you want to get anywhere. Good thing Espa Roba joined Duel Links with his trusted Jinzo!
- Difficulty Spike:
- Once you pass Stage 38 in the DM world, Standard Duelists become much more difficult to beat and only get tougher as you progress.
- The ZEXAL World does NOT play around. The AI has been reported at numerous levels using very dangerous Xyz monsters such as Tornado Bird, Castel the Skyblaster, Evilswarms and full-powered Madolche with their hilariously broken Madolche Salon and Puddingcess combo. The AI also is able to make multiple, complex chains of moves with the cards in mind. Even Level 33 Standard Duelists, which are still easy to beat in other worlds, shows a clear improvement in ZEXAL World and ARC-V World, when they are using Xyz or Pendulum-based decks, cleverly using monster removal and stacking ATK boosting effect to easily clear your field and inflict large damage.
- VRAINS World also becomes significantly more difficult at higher stages, with few of the NPC decks including World Chalice, but worst of all, Live☆Twin/Evil☆Twin.
- Epileptic Trees: The fact that the Paradox Brothers, who were not able to be challenged at Jump Fiesta like Yami Bakura, Yami Marik, and Pegasus, were added opens up endless possibilities for other characters from the manga or anime to be included as well. Spinoffs are also speculated, as Para and Dox appeared in Yu-Gi-Oh! GX as well as the original series. This was later confirmed with the addition of characters like Arkana and Bonz and a new GX world.
- Fanfic Fuel:
- Considering the cast of Arc-V, how would they react to the other worlds, like a world where the Academy was simply a duel school, the unification of Neo Domino City's citizens, a Heartland that wasn't decimated. Not only that, but what about the existence of the original Domino City or the world of Link VRAINS. Going one step further, how would the cast react that two worlds who took the game of Duel Monsters, and changed it to create Rush Duels.
- With Vrains proving that each of the series are now connected through Duel Links, crossover fanfiction using the game as a hub world that lets the casts of each series meet in general is a popular topic.
- Fridge Brilliance:
- Duel Links being created by Kaiba in-universe means that things that are out-of-place or out-of-character can just be how Kaiba sees them.
- While implied, Yami Marik isn't explicitly confirmed to be an NPC, as he asks Kaiba if he revived him and Kaiba says if he did he could erase him on a whim. Given Kaiba's obsession over resurrecting Atem in Yu-Gi-Oh! The Dark Side of Dimensions, including making a virtual copy of the Pharaoh, either way, it could be practice for that attempt.
- The event for regular Marik suddenly grants Yami Marik his original voice filter from the anime (in the English dub at least). While no explanation for the filter is ever given within the context of the anime, in Duel Links it makes sense considering Yami Marik is essentially a Living Memory, something supernatural in nature that should no longer exist, but still does.
- Why is Jack using Stardust Dragon the only time the monster’s usual summoning chant and attack/effect names aren’t used. Because unlike those other times, Jack wasn’t gifted the monster on the behalf of its normal user, so he didn’t give a rats ass about embodying what they stand for and simply treats it like another monster in his deck.
- The first Alt Style character in Duel Links comes from VRAINS, where characters often change the look of their avatar during the series.
- Fridge Horror:
- Ishizu invokes this in her appearance, berating Kaiba for recreating her Millennium Necklace and Battle City, as it means that Yami Marik and the misery that followed have also been recreated.
- If Arkana's unlocking speech is any indication, which starts with him glassy-eyed and silent, Marik forgot about him completely and never released him from mind control/the Shadow Realm until after the tournament was over and/or the Items were scattered.
- The fact that Duel Links can revive the dead and forces memories of alternate dimensions on people (as shown in DM) has terrifying implications for the worlds of GX, 5Ds and Zexal if (when) Zarc gets revived.
- Game-Breaker: So many it has its own page, though not all of these apply at any given time due to updates.
- Goddamned Bats:
- The level 27 Standard Duelist deck Brutality LV3 and the level 33 deck Heart of the Underdog, both of which operate on similar principles of using low-level Normal Monsters for beatdown. They both also back those monsters up with annoying removal cards such as Order to Charge and Attack of the Cornered Rat, making them very difficult to auto-duel against. Finally, they both run Heart of the Underdog, which lets them draw additional cards during their Draw Phase if they draw a Normal Monster... which they have a lot of, so if they play it and survive to their next turn, you'll have to sit through a load of animations and listening to the Duelist go "I activate a Continuous Spell!" over, and over, and over. The main saving grace is that their monsters tend to be on the weak end and are easy to dispose of with your own removal cards, so most competent decks can run them over and they end up being more laboriously annoying than dangerous.
- Reverse Trap is another NPC deck that can cause a lot of problems. In addition to powerful stall Traps like Windstorm of Etaqua and Curse of Anubis to neuter your attempts to attack, the deck runs Flash Assailant, a powerful 2000-ATK beatstick, along with a ton of ATK-reducing effects to beat over your monsters. The deck's trump card is the titular Reverse Trap, which reverses ATK and DEF gains and reductions to allow Flash Assailant to potentially turn its negative effect into a stat boost and win battles it otherwise wouldn't while also making your own ATK-boosting effects into liabilities. Fortunately the deck isn't very good at closing out games if you simply keep pressuring it and ensure they can never combo Shooting Star Bow - Ceal or Twin Swords of Flashing Light - Tryce with Reverse Trap, so the AI runs out of steam more often than not, but it's quite a slog getting there.
- Aqua Chorus runs multiple copies of Time Machine
, forcing you to beat over the opponent's monsters multiple times to hit their Life Points, and can flood the board with Gilasaurus
while stalling even further using Harpie Lady 3
and the self-reviving Twin-Headed Behemoth
. As such, duels against this deck often drag on for far longer than they need to given that the AI doesn't have a single threatening monster but will happily spam them nonetheless. - The level 39 AI deck Coin of Destiny runs the combination of Second Coin Toss and Time Wizard for a fairly consistent board clear, and if you try to play around it while going first, they can use Amazoness Trainee boosted by Graceful Dice to start threatening you. The deck isn't particularly dangerous due to low ATK values all around, but watching your monsters get blown away by Time Wizard can be pretty aggravating regardless, especially if you weren't expecting it, were using Auto-Duel, or simply didn't check what deck you were facing.
- Goddamned Boss: Yuri's Raid Boss event is notoriously annoying to farm thanks to him running Predaplant Flytrap
, which can seriously mess up a player's scoring attempts by removing their key monsters and play merry hell with the Auto-Duel AI. He naturally also runs Starving Venom Fusion Dragon at higher levels, which can single-handedly end your attempt if you didn't bring non-destruction removal for it, though being a Raid Boss means that losing against him doesn't mean much as it would otherwise. - Good Bad Bugs:
- A Mokuba audio glitch resulted in his attacking dialogue for monsters getting mixed up, with the Luster Dragons swapping roles and Alexandrite Dragon becoming Shinato, a card Noah used in the anime.
- A Yami Bakura glitch on day 1 of his Destiny Board event in version 1.7 resulted in him breaking the ratings scale
◊ for levels before it was fixed.
- Harsher in Hindsight: Jim's absence from GX post-Season 3 is made even harder to handle after his event reveals he was so traumatized by his failure to defeat the Supreme King that he actually quit dueling all-together.
- Heartwarming in Hindsight: The DM world Paradox event happened shortly after Kazuki Takahashi passed away, and had a conversation where Pegasus expresses to Paradox that while he's already gone in his world, Duel Monsters would still exist and continue to thrive. The event was scheduled before Takahashi's passing, but took on new meaning afterward with the promise that, just like with Pegasus, the game he created would live on even after he was gone.
- Ho Yay:
- A few duelists have voice lines that come from them interacting with their romantic interests in the anime, and yet can be directed to their opponent regardless of gender. Blair can swoon over a girl and call her dreamy, Anna can act like a Tsundere and stop herself from asking a female duelist on a date, and Alito can fall head over heels and try to make moves on a male opponent like he did with Tori (though in his case, acting this way towards another guy isn't new behaviour.)
- One of DSOD Yugi's pre-battle quotes is him mourning the death of the Pharaoh, but can just as easily read as him recovering from a nasty break-up.Yugi: Of course I miss him. Things ended so suddenly between us. I wish I had another chance to tell him what he meant to me.
- I Knew It!: Many players predicted a GX world would be added down the line, as well as a 5D’s world. And, as of September 2020; ZEXAL world has been added, too. Then all the other series after that.
- Just Here for Godzilla:
- Some players are only here for the ability to play as their favorite characters and to see the characters interact.
- Other players are Rush Duel enthusiasts that are only here because it's a Rush Duel game with continuing support outside of Asia. Or are here to play Rush Duels as their favorite characters.
- Les Yay: Standard Duelist Jess professes her admiration for whichever Duelist you're playing as in her introduction, and her voice and dialogue is on the flirty side with them. It becomes this trope whenever you're playing as a female Duelist.
- Memetic Badass:
- Thanks to a typo/glitch
in version 1.7's first Destiny Board event, Yami Bakura has been imagined as a duelist so difficult he starts with 5 Exodia pieces and losing to him deletes your account. - In 2021 a reddit user under the name Elfoman became one after a string of successful leaks of the next main and mini boxes (For context, Konami changed the way updates work in a way that boxes cannot really be datamined anymore). Because of this he rose to the level of master leaker in the eyes of the community. He apparently was caught after his last leak included one card that Konami does not release, but the memory of what he has done remains with the community.
- Thanks to a typo/glitch
- Memetic Mutation:
- "With no monsters left on the field, I summon Dark Magician and attack for game."Explanation
- Beaver Warrior is talked about as if he was the best card in the game, similarly like Jerry Beans Man in the TCG (the latter being Hilarious in Hindsight considering he did end up becoming the #1 used card in the first KC Cup).
- Chazz posting which usually consists of Chazz writing poems to Alexis.
- Jaden being the true master of magicians after an event accidentally gave him a Skill that belonged to Yami Yugi and related to Dark Magician.
- "Apologems", a term inherited from other gacha games such as Fate/Grand Order, is used every time there's server maintenance or just said at even the slightest annoyance on the game as a way to try to get free gems.
- Another 4chan meme is "Jack Fatlus" which is Cloudian Altus with Jack Atlas hair.
- "You're a third-rate Duelist with a fourth-rate Deck" has become a popular competitive gaming taunt and Kaiba's fanon catchphrase for being such a Jerkass thing to say that it Crosses the Line Twice.
- "Do you know the surrender icon? You should touch it", a line added for Kaiba in the 2025 DM World update, is already well on its way to being the second coming of the above line.
- Microwave-related memes began to pop up in Summer 2021 after an update to the game caused an incredibly high amount of reboot errors, to which Konami's response was to make sure players' microwaves were not active close to their router or wi-fi device.
- In general, many players have memed the game's bizarrely frequent bad English that often results in some of the translations being unintentionally blunt, confusing, and hilarious.

- Narm:
- Yami Bakura and Yami Marik are notorious villains and threaten their opponents accordingly, but none of the Standard Duelists seem to take them seriously. Most of the time, they simply comment about having to do better at their game even though they're being threatened with a trip to the Shadow Realm, and others wish these mass murderers good luck or remind them to have fun.
- Never Say "Die" is generally in play, which leads to Marik making awkward threats like "So do you want to be gone from this existence?"
- The taunt button can invoke this in serious duels, like having Jaden tell Yubel "The egg-wich is mine!" or having Arkana talk about Dark Magician when it isn't on the field.
- Yuya's summoning chant for Odd-Eyes Raging Dragon is delivered in such a happy tone that people don't feel the hype they're supposed to feel, since in the anime, Yuya has always said the chant while he's Awakened. The lack of Yuya's Awakened state in this game also puts off some people from the immersion because Odd-Eyes Raging Dragon is supposed to represent Yuya's blazing and violent rage. This also goes for Odd-Eyes Rebellion Dragon, which Yuya also primarily used while Awakened and whose chant does not fit his smiling cut-in at all.
- D/D/D Doom King Armageddon is assigned as Declan's ace monster, meaning it gets a summoning animation. Unfortunately, Armageddon's rather simplistic design
means that it's basically a huge slab of crystal with no movable parts aside from its head (and even then only barely), meaning the summoning "animation" just consists of the camera panning over Armageddon while it awkwardly stares at the viewer. Granted, the camera angles at least attempt to make it look impressive, but compared to the more dynamic animations of other ace monsters it's very obvious they couldn't do much with it.
- Narm Charm: Invoked by the English translation. Although a lot of lines are more faithful to the original Japanese manga/anime, it also inserts many of the lines from the 4Kids dub to appeal to nostalgic English dub or Yu-Gi-Oh! The Abridged Series fans, such as Arkana's Dark Energy Disks or one of Bonz's victory lines being "You didn't stand a ghost of a chance!"
- Nightmare Fuel: Enjoy.
- Rescued from the Scrappy Heap:
- Ice Barrier monsters in the traditional card game were essentially forgotten about save for their Synchros. Ice Barrier monsters in Duel Links, by contrast, see more than their fair share of play due to a great magic card in "Magic Triangle of the Ice Barrier," powerful two tribute monsters with great effects, excellent drawing power/potential and good synergy among its decks. It's not exactly top tier, but you'll see quite a few online duelists use them regularly.
- In the same vein, while HEROs aren't Low-Tier Letdown status and are arguably the other way around, first-generation Elemental HERO monsters were for being unnecessarily gimmicky. While they aren't top tier either, the reduced deck size makes it easier to get the materials you need for their fusions and also allows for a much more focused deck. In addition, they released the more useful and streamlined cards like Blazeman early and gave Jaden a skill to drop Skyscraper on the field to help ease the problem.
- Prior to its modern support, Yubel in the real-life card game was considered an Awesome, but Impractical gimmick at best and a bricky mess at worst. Duel Links solved those problems with the reduced deck size, making it much easier to draw the cards you need, and also gave Yubel (the character) a skill to shuffle the evolved forms, which otherwise sit like bricks in your hand, back into your deck and search the base Yubel in their place. Combined with Fire King and Nephthys support to destroy Yubel in your hand, you can easily get Terror Incarnate onto the field without having to waste resources summoning the base Yubel, making the deck vastly more consistent and powerful.
- Yubel and Neos' ultimate form, Neos Wiseman. Having to summon TWO high level monsters on the field is, even in Duel Links, very clunky. And then Jaden, Yubel, and Jaden/Yubel acquired the skill Eternal Bond, a skill that allows them to Normal Summon Yubel and Elemental Hero Neos with no tributes. Not only that, but upon summoning them, they can either auto advance Yubel to the next form face down and ready to be Flip Summoned, which re-triggers the skill, or to acquire a copy of Neos, Super Polymerization, or spawn a Miracle Fusion. The Miracle Fusion is important as it is the primary way to summon Elemental Hero Neos Kluger, an actual Fusion of Yubel and Neos, who upon leaving the field, summons Neos Wiseman. It shows how much of a boost the skill gave them as Neos Kluger released as a Limited 3, you only realistically need 1 or 2 in the Extra Deck.
- War Rocks were considered to be about 10 years out of date on the day they debuted in the TCG, due to their clunky Battle Phase-focused playstyle being wholly unsuited for the combo- and negate-centric metagame. On the other hand, the lack of a Main Phase 2 and heavily-curated card pool of Duel Links pushes a slower and more battle-focused metagame that proved to be just right for them, and the lower LP makes their boss monster Meteoragon a legitimate threat when it hits the board, making the deck much better regarded in their Duel Links debut.
- Dumon and his Star Seraph deck were both considered extremely forgettable in their anime and TCG appearances, with Dumon being a Memetic Loser and the Star Seraphs being overshadowed by any number of other Rank 4-focused decks. However, in Duel Links, Dumon has some extremely potent Skills for boosting Star Seraphs' playmaking ability while still having clear weaknesses and counterplay (unlike the horrifically broken Tachyon Dragon Domination used by Mizar before him), letting him and his deck be a strong contender while also not overcentralizing the meta around themselves to the same degree.
- Ghostricks started out as a joke due to the lack of Main Phase 2 forcing them to choose between flipping themselves face-down and trying to deal damage to the opponent, which hamstrung their already poor speed and power and made them weak even by early Duel Links standards. However, the release of the Starving Venom box not only gave them some of their better support, but also gave them a Skill that let them simply play a monster from their Deck, thus enabling the cards in your hand to be Normal Summoned, while also flipping your monsters face-down during the End Phase of a turn where this effect was used. This gave them the speed and consistency they lacked even in the TCG/OCG, making them a viable contender.
- Salvaged Story: After both ARC-V and VRAINS wrapped up with endings deemed esoteric for the former and Cut Short for the latter, Duel Links works to resolve both in a more satisfactory manner. The ARC-V world gives the characters trapped inside Yuya and Zuzu the chance to live separately again, with other characters acknowledging this, and the VRAINS world is an outright continuation of the story.
- The Scrappy:
- GX Standard Duelist Zachary is a smug, obnoxious elitist scrub that believes himself above everyone else and rubs your defeats to him in your face, but when he loses, he'll start whining or blame it all on his cards. He also seems to have trouble learning a lesson. Long story short, he's Obelisk Blue Chazz before his Character Development, only worse and with a more annoying voice.
- DM Standard Duelist Andrew is an Insufferable Genius, and it's grating to lose against him.
- Scud, a character from the Dark Side of Dimensions movie, was already clearly designed to be unlikable and not someone you'd feel bad about being erased by the villain, but players of Duel Links found more reasons to dislike him once he was added to its world as an LD. Among those are him being added as a full character when more popular ones haven't been (even within that world he's playable before Yugi, a main character), his tedious unlock requirement detailed just above, and feeling like a waste of effort since he barely has any unique lines, no interesting drops, and unique skills that are worse versions of common ones. Very few non-ironic fans of his inclusion have been seen so far, at least among Western players.
- Scrappy Mechanic:
- Certain rare, powerful cards can only be won by defeating a Legendary Duelist and getting lucky with the card drops, with a higher chance on higher-level duelists. The problem is there are tons of Junk Rare cards that they all possess that you're likely to get tens and hundreds of before you even hope to see one of those cards. Luckily, a July 4 update allows you to trade Tickets from Ranked Duels to obtain Legendary Duelist cards.
- The four/five victory streak needed to progress to the highest ranks in PvP, Platinum, Legend and King of Games. You need to be lucky enough to not get paired up against a deck that outright counters yours, get a good starting hand in each duel, and don't get screwed by the exploit-abusing duelists. While the Platinum ranks are more lenient with the requirement, for the Legend ranks you need a five win streak to climb to the next rank and there are three levels in Legend. The worst part? If you get a three loss streak you drop a rank. The requirements have since been eased a bit.
- A subtle one, but some cards will follow rulings from the OCG as opposed to the TCG rulings, which can trip up a few TCG players. For example, "Fusion Tag" has its effect able to be used, correctly, for when the target is used as a Fusion Material, not just for a Fusion Summon (there's a difference - Contact Fusions such as "XYZ-Dragon Cannon" use Fusion Materials but aren't Fusion Summons). The latter case was incorrectly printed on the card in the TCG.
- The card trader is becoming this to some, as with many updates to its stock the card rotation is random and there are players upset at seeing repeats of cards they already have 3 or more copies of while others (especially for sets like Gemini or Aromages which have a lot of their support be exclusive to the card trader) can go weeks or even months without appearing. The Regular Inventory feature helps with this, but the issue still remains for newer cards that are not in the Regular Inventory yet.
- Any event in which the prizes are up to the lottery. The issue fans have with the lottery is the placement of gold or keys in the drawing, which squanders chances of getting the limited edition cards available in a certain time-frame.
- The 5D’s characters have their ace cards (save Leo, whose box just gave players his Power Tool Dragon, though eventually crept up when Life Stream Dragon was added) locked behind a Skill that adds two Tuners and one copy of the ace dragon to the Extra Deck. These Skills screw up deck consistency (unless you build around it) and force players to fatten up their decks for no reason. Trudge's Skill is even worse because it removes all OTHER cards in the Extra Deck just to run one Goyo Guardian, making it worthless. While Jutte Fighter itself is fine for a generic Tuner monster, players still don't see this as a fair enough trade-off. At least, until Konami updated Trudge's Skill in May 2019 to no longer remove all the other Extra Deck cards. Later skills that give ace monsters at least provide other benefits than just adding the cards to your deck (with some, such as DSOD Kaiba's buffed Ultimate Dragons, becoming viable in their own right).
- The time limit in PvP mode is this to some. While it does start at 180 seconds (3 minutes), there is the annoying trait of it penalizing you depending on how long your turn takes. This can be especially frustrating for players who use slower decks and end up losing due to not having enough time to conduct their full strategies. It becomes even worse if you have a bad connection in the middle of a duel, at which point the time limit will run down anyway with you being unable to attack, activate card effects, or even end your turn.
- Another problem players have is the abundance of bots (CPU-controlled duelists in PvP mode), duelists who use decks with many powerful cards and more often than not have perfect answers to your every move. A lot of their decks include cards like Watt and Trickstar monsters that can attack you directly, three copies of traps like Floodgate Trap Hole and Paleozoic Canadia, and Golden Castle of Stromberg. There's no end to the number of bots in Casual Duels, although these days they also run rampant in PvP events too, which has the potential to ruin high win streaks if you can't defend yourself.
- Gems are shared across both Speed and Rush Duel cards. This means if you want to get into Rush Duels, you have to spend gems on both sides. This has caused some players to opt out of Rush Duels entirely, only getting the bare minimum to claim rewards from the SEVENS cast.
- Inexplicably, Skills are distinct from card effects in that they do not cause an open game state whatsoever. This means that they are functionally completely unrespondable and there is no window for an opponent to start a new chain when a Skill effect resolves. This has become much more egregious later in the game's life when Skill balance has become drastically more lopsided, as many Skills can do things such as play cards to their field from either the Deck or thin air for free and the opponent has to sit there and take it. Konami has taken steps to remedy this by making Skills play monsters in face-down Defense Position but allowing the user to Flip Summon them in the same turn, which adds a priority window where the opponent can respond before the monster becomes usable.
- Sequel Difficulty Drop:
- The first D.D Tower event, FIRE Dimension, was Nintendo Hard. You did not recover Life Points between Duels, and if you lost all of them, you had to either wait until your LP fully recovered in 3 hours or use a limited-supply LP potion. Worse, the higher floors had monsters use proven metagame decks, and if you wanted all the rewards guaranteed, the missions gave exactly enough points to go through the rewards box three times, even though many of them are tedious or require a specific Awesome, but Impractical strategy. The follow-ups, WATER Dimension and all the subsequent Dimensions, made things a lot easier by reducing the strength of the decks, being far more generous with mission points, allowing you to play even with 100 LP, and introducing a randomly spawning D.D. Invader who you could defeat for mission points and a full health restore.
- Duelist Chronicles underwent a similar difficulty drop from Duelist Kingdom to Battle City Begins. The former had buffed versions of characters' decks inspired by the metagame at Level 40, as well as powerful, AI-exclusive skills, while the latter kept the decks more accurate to the source material at the cost of difficulty. The best example can be seen with Mako's deck. In Duelist Kingdom, he ran field-swarming Hammer Shark and the field-destroying Levia-Dragon - Daedalus, making him a challenging fight, while in Battle City, his strongest monster is The Legendary Fisherman, which has lower ATK than Levia-Dragon and a weaker effect.
- Also in Duelist Chronicles, the King of Games Optional Boss in Battle City Showdown had the skill Divine Advent, which plays a random Egyptian God at the start of his third turn, potentially creating a massive, insurmountable advantage against unprepared players (at least, if it was Obelisk or Slifer). In the Society of Light event, the same boss had the skill nerfed significantly: it now only summons Slifer (which has variable ATK and isn't targeting immune, unlike Obelisk) and is now treated as a Special Summon, which means the summoned Slifer only lasts one turn.
- Signature Line:
- Even those with a cursory knowledge of the game will recognize Seto Kaiba's victory taunt, "You're a third-rate Duelist with a fourth-rate Deck!" Any scene that references Kaiba online will likely have someone in the comments making a reference to this quote.
- For fans of JoJo's Bizarre Adventure, Sartorius/Saiou's lines for Arcana Force XXI - The World, which were recorded ''after" his Japanese voice actor portrayed DIO, and thus had him fully commit to their hammy delivery ala his performance as DIO.
- Superlative Dubbing: Both language tracks are quite loved, as the return of the voice actors from older series show many of them Still Got It. However, the dub deserves a special mention as the returning actors from the anime have undergone Vocal Evolution over the years to give even stronger performances for the characters. In addition, the translation being more faithful to the original allows for a more mature take on the cast compared to the more toned-down versions from the anime.
- Marc Thompson as Z-one has been a particularly praised example, as Z-one's content in the original dub for 5D's was cut short, meaning he barely had a proper chance to play the character until Z-one's raid event in 2023.
- The same could be said for Billy Bob Thompson as Specter, who had been largely absent in Season 3 of VRAINS since his seiyuu was busy with theater work, as it allows him to show more of a range than what the anime gave him.
- Michael Liscio, whose performances as Yuya and his counterparts were once vewed with derision, has improved his takes considerably. Especially in regards to both Yuto and Yuri, making the former sound much less forced and edgy and the latter sounding much closer to the original Japanese depiction as a smug sadist.
- In the original dub of 5Ds, Jason Griffith was criticized for voicing Primo with the exact same voice he used for Shadow the Hedgehog. But returning to the role years later with more experience under his belt since then, one would be forgiven for believing he had been replaced, as he sounds much closer to Masakazu Nemoto's depiction of the character.
- Tainted by the Preview: The announcement of Rush Duel format coming to the game was initially seen as an interesting addition by some parts of the playerbase... until the official presentation for it at Tokyo Game Show 2023. Konami not only announced that Rush Duels will use the same currency (gems) as Speed Duels, but the first Main Box of the new world will entirely be focused on Rush Duel content, leaving Speed Duel format in a much longer, more stagnating metagame as well as a possibly longer content drought, as Konami is very selective about what cards are allowed to come to Speed Duel format. It's enough to where now some believe that splitting the playerbase between Speed and Rush formats so heavily could result in the game shutting down like Cross Duel.
- That One Boss:
- Several Legendary Duelists at max level, primarily for having powerful cards unavailable to the player.
- Mai Valentine at Level 40 (and even Level 30) is one of the hardest Legendary Duelists to beat, let alone farm for Random Drops, because her Amazoness Village can replace any fallen Amazoness once per turn, she runs plenty of Trap Cards to revive them from the Graveyard, and she has cards like Amazoness Fighting Spirit and Amazoness Spellcasters to overpower most monsters you could throw at her. Unfortunately, two late-stage missions require you to win 3 consecutive victories against her and achieve 3 Quick Victories with Joey Wheeler (in two of your turns. Fortunately, these don't have to be consecutive) respectively.
- Ishizu Ishtar's Level 40 deck, much to the chagrin of those seeking to build a Gravekeeper deck. It features Necrovalley to boost her Gravekeepers by an unprecedented 500 ATK and DEF, as well as a hard-to-defeat boss monster in Gravekeeper's Visionary, which gains power for every Gravekeeper in the Graveyard and can protect itself from destruction by discarding Gravekeeper's monsters. Gravekeeper's Assailant also has its effect readily accessible to strike your powerhouses at their (usually) weaker DEF.
- Seto Kaiba's Level 40 deck is regarded as one of the hardest to beat. He runs the 1900 ATK Vorse Raider, as well as Cost Down to easily bring out a 2400 ATK Luster Dragon #2 for no Tribute or his signature Blue-Eyes White Dragon for only 1. And in case you try to overpower him with a monster, he also runs D.D. Warrior to remove any of your monsters or Enemy Controller to steal your monster and finish off your Life Points, or protect himself from attacks by switching your monsters to defense mode. Unfortunately, the latter is also one of his drops and a metagame staple. Also, like Mai, you have to win 3 times consecutively against him for a late-stage mission.
- Level 50 Yami Bakura runs a Dark Master Zorc deck revolving around disruptions, Dark Necrofear, Zorc's dice rolls, and Destiny Board. Destiny Board of Doom is also in effect, forcing you to play on a time limit if you're unable to remove Dark Necrofear from his graveyard. His Level 40 Evil Incarnate Deck in his Zombie mini-event was also notoriously difficult, running multiple copies of Tribute to the Doomed, Book of Life, and Sakuretsu Armor to stymie whatever the player tried along with 1800 ATK and up monsters.
- Alexis Rhodes is no joke. If you can't negate her rituals or have a backup plan to destroy them, they're going to hit hard, instantly destroy your monsters, and be well protected by their Ritual spell card. She also has Gemini Elf to back her up and other monsters with effects to irk and annoy you.
- Level 50 Yami Marik starts with Ra in Sphere Mode and can summon the Battle Mode on turn 1, and his other cards include stuff like Michizure, Dark Jeroid, and Viser Des. The only saving grace is that you could fight him indefinitely until you defeated him.
- Level 40 Zane not only has his Cyber Dragons, as in the original ones, the ones that Special Summon themselves but also has Power Bond and the Cyber Dragon fusions. If you do not have anything ready to stop his monsters, chances are he will OTK you with Cyber Twin Dragon's second attack or Cyber End Dragon's 8000 ATK with piercing.
- Level 30 Aster's strategy focus on keeping Clock Tower Prison on the field with enough counters, preventing you from dealing damage to him. Level 40 Aster added a ridiculously powerful Fusion monster on top of that. Sure, Level 40 Aster sometimes bricked, but if he gets the combo going, you might as well just give up and take the loss.
- Level 40 Playmaker is stone-cold ruthless, capable of effortlessly spamming out the majority of his Extra Deck in a single turn while shredding through your field. Between multiple options to fill his board, Cynet Mining to search out whatever combo piece he's missing, and the trio of Code Exporter, Micro Coder, and Code Generator to gain massive advantage off his Link spamming along with Code Radiator to debuff your monsters down to nothing, once he starts his combos he'll probably finish you off within the turn.
- Level 40 Yuo is fairly challenging due to him running powerful monsters like Daigyakutenno Megami and Cyber Dragon in his main deck to keep up the pressure, while also having Metarion Vritrastar and Metarion Ashurastar in his Extra Deck as powerful boss monsters that are very tough to deal with unless you came prepared and drew your outs. His monsters being able to counter specific Types also allows him to pull out surprise OTKs unless you play decks that he can't shut down this way, which often requires significant Box investment. He also packs some powerful Spell and Trap cards, including Imaginary Arc Turbo to pump his monsters up by a huge 1500 ATK and Imaginary Arc Turnback to potentially revive his Fusion Monsters.
- Level 40 Zuwijo can be a chore to face due to his ace monster, Voidvelg Requiem, being devastatingly powerful at 3400 ATK on his turn (upped to 4000 if the player is unfortunate enough to have a LIGHT monster in play), paired with him having numerous ways to recur the thing from his Graveyard, meaning you're not getting rid of Requiem once he draws it (barring fringe cards like Forever Freeze to bury it on the bottom of his deck, and that's assuming you get it before he puts Requiem on the board). He also runs the Legend Spell Dark Hole, which lets him wipe out the board if he draws it and then make a push for an OTK.
- During his Cyberdark event, Level 40/50 Zane's Cyberdark deck allows him to lead with a 2000+ ATK monster, usually alongside a Field Spell that offers great protection for his Cyberdark monsters. Unless your opening hand is good, you most likely will have no way to deal with his Cyberdarks quickly, which usually means a loss for you.
- In the Tag Duel Tournament event, Joey and Mai are the bane of many players seeking to win Master level despite being only the second of five opponents (and if you lose any game in Master level, you have to start from the beginning). Mai runs a deck similar to her Level 40 Amazoness deck, including the reserve-spawning Amazoness Village, except it's even worse since she also has Amazoness Heirloom, which gives an Amazoness the ability to destroy any monster she attacks while protecting her from destruction by battle once per turn. Plus, both of them have a Skill that revives one of their partner's monsters once per Duel. All these factors make their monsters hard to overcome. Notably, Konami nerfed Mai's deck one day after Master level was released, but their That One Boss status remains.
- Inglorious Bastion's level 40 deck has been proven very difficult to farm against; combined with the speed at which he mills himself can prove fatal to either yourself if he brings out Kasha or himself if he decks out, preventing you from obtaining the maximum amount of points against him. Even his level 30 deck can bring out a huge beater directly from the Deck easily - depending on what farming deck you use, it's very possible he can take you out in the first three or five turns.
- Epic Yami on day one had proven to be so powerful that not even a single current farming deck was able to take him out consistently without massive luck. Even then, his deck had answers for almost every currently known variant. Konami had to nerf his deck so that players can actually beat and farm him.
- Dark Signer Kalin runs a near-full-power Infernity deck, including the key cards that made it a long-time Game-Breaker in the OCG and TCG. Infernity Launcher allows him to summon 2 monsters from the Graveyard once the handless condition is fulfilled, and Infernity Archfiend searches any Infernity card from the deck when Special Summoned, including Launcher (and Archfiend also comes with a Miracle effect in which it Special Summons itself if it's the only card in hand during the Draw Phase). This means he can easily put out a full board of powerful monsters with alarming regularity, and if a player is unlucky enough, he can even do it on his first turn with the right cards. This was particularly bad during the Earthbound Immortal event, where he became a Goddamned Boss due to having Life Points inflated to Raid Boss levels (40000-70000 LP normally, with Lv. 500 and Lv. 1000 variants going up to 125,000 and even 250,000 LP), a 5 turn limit to deal damage to him, all while taking a very long time to complete his Infernity combo chains each turn and repeatedly summoning a full board each turn after fulfilling the handless condition.
- Kite Tenjo at lv30 and 40 in his roaming event already runs a rather consistent Photon deck, able to bring out Galaxy-Eyes Photon Dragon easily, and at lv40, if you are not careful or not lucky enough, you could end up seeing him bring out Neo Galaxy-Eyes Photon Dragon. Farming decks usually have trouble if GEPD remains face-up on the field for a long time, and usually flat out fail the farming if Kite gets NGEPD out.
- Level 50 Celina during her first unlock event is armed with a full power Lunalight deck, which includes all the Lunalight cards that players don't have access to. This makes it really easy for her to bring out her Fusion monsters (particularly, her Leo Dancer, which is an untargetable and indestructible 3500 ATK monster) and steamroll your deck. Even at Level 40 her deck is almost at full power. Most players have to bring Extra Gate, an unsearchable Spell card (so you better hope you open with it or get it before she summons any Fusion) to counter her deck and farm her drops.
- Level 40 Rin runs a full Windwitch package along with both of their Synchro Monsters, meaning she can and will often pull out Diamond Bell as soon as possible and destroy two of your cards with its effect while burning your LP. If she pulled it off with Ice Bell, she'll still have a Normal Summon available, in which case you're probably dead if you don't have heavy-duty removal or disruption ready. And if the player goes second, she also runs a defensive Gusto package to make herself harder to OTK before she combos off on turn 3. This is in stark contrast to Lulu, who shares an unlock event with Rin and plays an extremely watered-down version of Lyriluscs even at level 40 (to the point that her strongest monster is a low-statted Normal Monster); this is particularly odd as the version of her deck you can use against Yuto and Yugo is a full-power Lyrilusc. However, Level 50 Lulu more than makes up for this as she can and will OTK you with Assembled Nightingale if allowed to set up her board.
- Several Legendary Duelists at max level, primarily for having powerful cards unavailable to the player.
- That One Level:
- Missions 57 and 58 require the player to win against Mai at level 40 and Kaiba at Level 40, respectively, 3 times in a row.
- Mission 59 requires the player to summon Perfectly Ultimate Great Moth, a 3500 ATK monster who can only be summoned through very weak cards staying on the field for up to 5 turns. It's slightly easier if you have Weevil's skill that halves the time limit or play a low level gate duelist, but getting the card is a pain in itself. It gets better, using Cocoon of Ultra Evolution doesn't complete the mission.
- That One Sidequest:
- Several Duelists are an absolute pain to either unlock or make playable. Not for nothing did log-in events start giving out Character Unlock tickets.
- Unlocking Bastion requires you to achieve 50 wins total with 3 or less cards remaining in your deck.
- Unlocking Scud requires you to banish 300 of your opponents' cards total.
- Making Yubel playable, at least after the event that introduced them to the game, requires the player, to fulfill the following quests: 1) achieve a comeback victory against her using Jaden, 2) summon Rainbow Dragon as Jesse while playing against Zane at level 30, 3) summon Cyber End Dragon as Zane against level 30 Jesse, 4) perform 2 fusion summons in one duel against Yubel as Jaden, and 5) summon Elemental HERO Neos 3 times in one duel against them at level 30. Adding insult to injury, this means unlocking Jesse and Zane; the former requires unlocking Pegasus, while the latter requires unlocking Syrus and Aster, as their unlock missions involve playing as the respective duelists.
- Making Jaden/Yubel playable requires the aforementioned Yubel. Further, they also have the stipulation of summoning not just Yubel in battle against a level 30 Jaden but also the boosted forms of Terror Incarnate and Ultimate Nightmare. If the player failed to get them during the event they debuted in, or joined the game after the event, then the only way to obtain these cards are through ultra-rare prize drops via Yubel or Ranked Duels. If players manage 100 Ranked wins then they can get an Ultra Rare ticket but this only resets at the end of the month.
- Unlocking Leo is very simple, if a little time consuming depending on luck, but unlocking Luna requires you to WIN 100 duels as Leo.
- Unlocking Syrus requires you to use Elemental Hero Thunder Giant against Syrus at the Gate. Problem is, it's an SR rarity card that is currently only available as drop from Jaden Yuki, meaning until you get lucky with the drop, you're not unlocking Syrus anytime soon.
- Similarly, unlocking Zane Truesdale requires you to use Pair Cycroid against Zane at the Gate. Pair Cycroid is also an SR rarity card currently only available as drop from Syrus. Which means not only you have to get Syrus at the Gate first, you also have to be lucky with the drop first. You also needs to use Rainbow Dragon against Zane at the Gate, which requires you to unlock Jesse Anderson first, as the fastest way to get a complete set of Crystal Beasts necessary to summon Rainbow Dragon, is to use Jesse's level 4 skill. Fortunately, both Pair Cycroid and Thunder Giant have since become available through a number of card tickets, making the conditions much easier.
- Unlocking DSOD Yugi Muto is an ordeal that requires you to summon Deep-Eyes White Dragon against him while playing as DSOD Seto Kaiba. Deep-Eyes has a somewhat obtuse summoning condition of requiring one of your Blue-Eyes monsters to be destroyed by the opponent while it's in your hand, and since Yugi doesn't run removal cards as an AI, the only way to do this is to let him summon one of his big monsters, not get steamrolled by said monster, and let that monster destroy a Blue-Eyes monster by battle (which is another problem, since most Blue-Eyes monsters are bigger than anything Yugi runs) after you get Deep-Eyes into your hand.note And to make it even worse, the only copy of Deep-Eyes White Dragon available in the game is obtained by getting DSOD Kaiba up to level 30. You're probably much better off using a Character Unlock Ticket on him rather than unlocking him the intended way. This also extends to Aigami, who requires you to fulfill certain conditions against him while playing as DSOD Yugi.
- Most of the Signature Mon-themed card sleeves and playmats require you to play as the corresponding character 100 times or summon said monsters hundred times, respectively, to unlock them. For the latter, the progress can be quickened if you own multiple copies of them, but since most of them are UR, and since 5D's World, almost all of the Signature Monsters have to be bought from boxes, this can get very costly. For many players, they will either only have one copy or have to rely on skills that add those Signature Monsters to their decks. While many of the modern Signature Monsters are relatively easy to summon, difficult-to-summon monsters like Water Dragon or Elemental HERO Divine Neos makes unlocking their playmats not easy. What makes this worse is that monsters with restricted summoning conditions as well as Extra Deck Monsters have to be summoned by their preferred methods to make it count for the mission progress, so cheating them out without summoning them the proper way will not help you to speed up the progress (Sephylon, the Ultimate Timelord is particularly nasty about this since Z-one's Timelord deck basically forces you to cheat it out). Monsters that do not have summoning conditions, however, can be summoned in any way and it will count to the progression of the mission. And thankfully, Nail's Yggdrago doesn't have to be Maximum Summoned 100 times, but instead you have to win 100 duels with the middle piece in your deck.
- Several Duelists are an absolute pain to either unlock or make playable. Not for nothing did log-in events start giving out Character Unlock tickets.
- They Changed It, Now It Sucks!: The aggressive amount of Power Creep in the game's later years, particularly during the VRAINS and SEVENS eras, has turned away some players who originally got into Duel Links because they were sick of how swingy Master Duels felt with its power level, only for Duel Links to eventually turn into "Master Duels Lite" with the introduction of modern cards/archetypes and poorly balanced Skills.
- They Wasted a Perfectly Good Character:
- The way how Sugoroku/Solomon Muto was implemented in Duel Links received a lot of complaints, due to the lack of good event rewards and level-up rewards he would bring, his lackluster skills, how his Duel scenes and Event Story scenes are too similar to each other, his event bringing very little to the narrative, and his only summoning animation being for Blue-Eyes White Dragon, which is also used for four other Legendary Duelists (the two versions of the Kaiba brothers). He also isn't a Joke Character like Scud and Tristan, which is also why his reception is so harsh. While the lack of new summoning animations is justifiable, some people still wished The Legendary Exodia Incarnate would have received one, since Solomon has voice lines and skills associated with Exodia cards and the unlockable playmat and sleeves that come with him has The Legendary Exodia Incarnate on it, and after Blue-Eyes it's the next best thing to be a Signature Monster for him. Speaking of voice lines, some fans have expressed their disappointment about him not having voice lines for newer support cards of some of the classic monsters that were part of the deck he passed down to Yugi, like Gaia or Black Luster Soldier. The player base feel that the inclusion of Solomon is that of a "filler character" who was shoehorned into the game because DM World gets one every year, but given how full DM World already is, this has led to some people wish to move past DM World and concentrate on other worlds that aren't DSOD World or 5D's World.
- Brave Battler/Shima not being a playable character was met with disappointment, primarily because VRAINS has the smallest cast of the franchise, and the number of viable additions is further reduced by the fact that many VRAINS characters haven't had their decks printed yet.
- SEVENS has already put several of their side characters as non-playable characters, like both versions of Yosh, strictly keeping the Legendary Duelists to the main and major characters. Expect to see major characters like Otes and Yuga Goha in the future, but probably not Gakuto's retainers or Asana's other club members.
- Several characters have alter-egos as separate characters with their own style of dueling, like Jaden, Jaden/Yubel, and the Supreme King, or Kalin and Carly plus their Dark Signer forms. Despite this, other viable candidates for such treatment don't receive it; Zane pre-Face–Heel Turn, the Barian Emperor forms of the ZEXAL cast (although they are available as skills), and the ARC-V Alternate Universe versions of Alexis, Aster, Jack, Crow, and Kite. Zane is particularly egregious because Cyber Dragons and Cyberdarks have very distinct playstyles and don't synergize with each other, especially after their Divergent Character Evolution kicked in in the real game with Cyber Dragon's Xyz forms and Cyberdarks getting Dragon support. Instead both archetypes are all piled onto one character, and the result is that Zane's Level 40 deck is entirely focused on Cyberdarks while his Level 30 deck is entirely focused on Cyber Dragons (and yet has no Extra Deck at all), and his rewards list is stuffed with Ultra Rare and Super Rare cards, more than many other characters have.
- As of March 2024, Awakened Yuya being not available even as a skill, despite a sprite of him existing in the game, has been a disappointing topic for his fans, especially since the "Arc League" Duelist Road event (January 2024) added a skill that references his first Awakening, and the unlockable event playmat prominently features Awakened Yuya alongside his Odd-Eyes Rebellion Dragon. It doesn't help that Yuya's voice line for his Odd-Eyes Raging Dragon is delivered in a happy tone, which had been a disappointment for fans for a long time, since Yuya's first furious summoning of Odd-Eyes Raging Dragon has been a beloved Signature Scene for years.
- Sherry LeBlanc suffers from this upon release, with the consensus being that her implementation is even worse than Solomon's. While she's been a long-waited character and she's the first NPC opponent to be Promoted to Playable after a several years, she's released via a Duelist Road event, which means that her event doesn't contribute anything to 5D's World's narrative and she's not even acknowledged to have entered the world of Duel Links (she's not even the main focus of said event and she's only significant in ⅕ of the Duelist Road's story) until the Tag Duel Tournament event in May 2024. Her Level Up rewards aren't impressive, the box that comes with her debut heavily focuses on supporting the archetypes of Team 5D's rather than her own, and her voice lines neither include special interactions with other characters nor the usage of the Arthurian-themed Noble Knightsnote nor the French-coded Infernoble Knights (made particularly ironic by them being one of the best archetypes to use with her Revolution des Fleurs skill). The few redeeming features are that she can be unlocked very early in the event, her Signature Card is available as a Starter Decknote , and the extremely powerful Baronne de Fleur is locked behind a skill that requires the player to have Chevalier de Fleur on the field while the opponent has a monster on their field (meaning you can't put it out on turn 1 and stop your opponent from playing the game entirely) and it doesn't help you of summoning Baronne any easier, which prevents Sherry from becoming a Game-Breaker like Mizar before her, although the rerun of her event rectifies this by giving her a very powerful skill.
- They Wasted a Perfectly Good Plot: Fans have been largely disappointed that the ZEXAL events have been largely retellings of the anime storyline, especially when put alongside Arc-V and Vrains'' events which are post-canon and expand on the characters. Given the development characters from those worlds have received, it's been viewed as a wasted opportunity to get to see certain characters (most prominently the Barians) in a more casual environment or after they're redeemed. However, as of the Vector raid boss event's plotline, this view is starting to change due to massive plot revelations in both that event and the Marik event which correlate to it. Namely, that Duel Links can rewrite characters' memories and alter their personalities.
- Unexpected Character:
- With Yugi and Yami Marik being the only characters in the initial roster that nobody had, many were surprised to see the Paradox Brothers added to the game before their potential events. Tristan was also unexpected, as he didn't duel at all in the manga and only dueled once in the anime.
- One of the cards the player can win from Chazz is Ojamandala, a Spell Card that gives you back each of the three Ojama brothers if you pay 1000 LP. Ojamandala is an anime-only card; it's never seen proper circulation in the OCG and TCG. While anime-only cards aren't a new thing in the games, many weren't expecting a card like that in Duel Links, which up until the Chazz event, only features cards that are already printed in real life. Since then, many more anime cards started appearing in Duel Links.
- Similarly, up until the implementation of the "Future Horizon" box, Duel Links usually only feature cards that have been printed in both OCG and TCG. However, the box features a surprise appearance from not just one, but TWO Superheavy Samurai monsters who were not in TCG yet at the time the box is released, making their appearance in Duel Links the first time their TCG name and text are seen.
- Additionally, fans were stunned when lines for the Outer Entities
, two cards that aren't just implemented in Duel Links yet, they're so powerful they're both banned in real life, were found in the game, and given to Ryou Bakura's DSOD incarnation of all people for voice lines. A similar event was when Kalin Kessler was found to have a line for Trishula, a card he never played in the series, but was one of the reasons his archetype, Infernity, was so busted in the real-life game for a while. - May 2024 provided yet another case of this happening when the irl staple handtrap Ash Blossom & Joyous Spring was datamined, and promptly sent the playerbase into a panic. However, fears were quickly eased as it was soon discovered that the card (for now) was only to be used by the character Tour Guide of the Underworld while she's acting as the player's partner during certain events.
- October 2024 caused yet another instance of this when a datamine revealed that the old former Tier 0 deck, Darklords, were getting a ton of support, including the addition of a unique skill, and that their boss monster, the insanely powerful, easily summonable, and board-wiping card known as The First Darklord was now in the game's database. Days later it was revealed to only be a SR in the at the time upcoming main boxset, and was also completely unlimited. Needless to say, fans who were already shocked it was just in the game's code to begin with lost their minds.
- Almost no-one expected Lumis and Umbra to be added as characters, as most of their cards had already been added to the game and they hadn't appeared during the first Battle City event. This ended up being a pleasant surprise for most however as there was some genuine effort behind their inclusion, with all new sprites for the duo (since they hadn't appeared in Tag Force unlike every other playable character) and a nice animation if they get to summon Masked Beast Des Gardius, who is notably more animated than the other monsters.
- Jaden and Yubel were both expected individually; but getting Jaden/Yubel (Season 4 Jaden) was a welcome surprise with Matthew Charles doing a great job of conveying a more mature, yet heavily burdened young man that he didn't get the chance to originally due to the final season never being dubbed.
- Paradox was an unexpected addition for several reasons: there was no precedent for a movie villain like him to be added to the game, most of his cards had already been added long before him, and he had no previous sprites to draw from (Duel Links is his first video game appearance.)
- Ultimate Leo Utopia Ray being added to the list of cards with summoning animations, considering that it technically didn't exist in the anime as a separate card. It actually was Number C39: Utopia Ray equipped by the effect of ZW - Leo Arms, and it wasn't until many years later that the combination of both cards would be released in the OCG/TCG. Not only that, that combination only appeared once in the anime.
- Aoi/Blue Angel being the first event character for the VRAINS world was shocking for a multitude of reasons. The main girl of all the other eras was there when the world launched, and the first event characters were usually rivals to some degree (Zane, Jack, Shark, and Declan).
- Soulburner wasn't very surprising when the VRAINS world trailer was shown off, as he's a major character starting from Season 2. What was surprising, however, is that when VRAINS world actually launched, he was billed as the first character and not Playmaker.
- Sherry LeBlanc is now officially the first-ever event NPC to be implemented into the game as a proper character. She was originally just a CPU-controlled opponent for the Duelist Road event without voice lines, but her being announced as the unlock for late-March 2024 has set a brand-new precedent for character additions - even event NPCs are no longer off the table and have the potential to be added as playable characters in the future.
- Tour Guide of the Underworld being available as a secret Tag Duel partner in the Tag Duel Tournament event in May 2024 was something people did not expect at all.
- ARC-V had started with Zuzu available, and Celina got her own event not long after the world's release. Players were expecting Lulu Obsidian and Rin (Zuzu's other two counterparts) to show up at some point. Nobody expected them to show up in the same event, marking the first event with two separate unlockable characters, nor for them to show up before Yuri.
- Downplayed with Yuri, since he's always been expected to make the cut. While people speculated that Yuri might appear in 2024 (since Yuya, Yuto and Yugo were released in 2021, 2022 and 2023, respectively), the release schedule of 2024 made it look like that Yuri would appear in the next year, due to three ARC-V characters being already released over the course of 2024, with both, Lulu and Rin, being released in September. So it was a big surprise that Yuri would follow up shortly after in October 2024, the month when GO RUSH!! World was released (as well as the same month, SEVENS' Yuo is released).
- GO RUSH!! is an interesting case. Players did not necessarily deny the possibility of a GO RUSH!! world, but most were generally doubtful that Konami would go ahead with it only a year after the introduction of SEVENS World due to crossing uncharted territory: It would be the first world based on a currently-airing series, and it would also be the first world to predate an English release of its media. Several players also pointed to the absence of Fusion Summoning, as Fusion was introduced halfway through SEVENS and it seemed more plausible to drag out the SEVENS World story arc long enough for the power curve to hit Fusions before introducing GO RUSH!! World. Naturally, players were flabbergasted when Konami announced GO RUSH!! World at the Yu-Gi-Oh! World Championship Series 2024, and even further still when "Ancient Gear" and "Elemental HERO" were announced for simultaneous release, cards that not only heavily revolve around Fusion Summoning but are also very new in real life, with "Ancient Gear Golem" being the first Duel Links card to beat its physical print in terms of release schedule.
- While Flame was hinted long before his eventual return, nobody expected that he would be coming as part of a first-ever feature for the game: alternate costumes. The first of which being a new skin for Soulburner, now fighting alongside Flame.
- July 2025 marks the first time a cutscene NPC (as in, not duelable as an AI opponent for events) will become a playable character, in the form of the normal version of Marik Ishtar, who was only previously seen in certain events such as DSOD Bakura's event flashbacks.
- After 9 years of minor references here and there but no clarification, Konami announced at the 2025 WCS that they will be updating the DM World to include characters from the anime-only filler arcs. The first two new characters to be revealed in the update? Noah Kaiba and Dartz.
- In the Kaiba Urban outfit cutscene for using Dragon Master Knight, Princess Adena had a character model instead of just an anime screenshot, hinting that she'd either be an alternate style for Mokuba or her own separate character.
- Not only did no one expect Joey little's sister, Serenity, but no one could've ever dreamed that she'd have a line for Red-Eyes Dark Dragoon, a card infamous for being so powerful few could've seen it ever coming to the Speed Duel format at any point.
- Win Back the Crowd:
- A lot of old-school Yu-Gi-Oh fans picked up the game not only because it featured the original cast, complete with voice-overs, but also served as a return to a less special-summoning focused format for those disenchanted with the regular game's Power Creep or new summoning methods. Cards introduced from GX onward are selected so as not to overpower the original generation cards, and power cards from the original game have been excluded (e.g. the strongest instant-kill cards are single-target with various conditions or costs). Thus, cards and strategies that never saw any competitive use in the TCG, such as Flash Assailant or Guardian Statue, end up being extremely useful or even the focus of their respective decks.
- Another charm to the game is the Speed Duel format. With half a deck size, LP count, and no Main Phase 2 available to the player, it's a different style of dueling that when combined with the card pool, forces players to think up fun new strategies or make do with what is available. Furthermore, cards that were introduced such as Gladiator Beasts or Mermails are surprisingly balanced against other decks (with few exceptions) promoting a game that a lot of players can enjoy.
- While the implementation itself has drawn criticism, particularly in regards to its monetization, Rush Duel has been hailed as a strong revitalization for Duel Links, allowing players to take a break from the rapidly advancing power level of Speed Duel and enjoy a more straightforward, accessible, and distilled form of Yu-Gi-Oh! that still offers strategic complexity.
- The Woobie:
- Roland gets yelled at if you click on the KC status reports when nothing new's happened.
- Bella is a little girl with self-confidence issues, which can make you feel awful if Kaiba, Keith, or Yami Bakura defeats her.
- Evan is a confidence-lacking Slifer Red Student, without much money to afford a competitive deck. He can be extremely disappointed with himself on defeat, sometimes even asking you to give him your Deck out of despair. This is even worse if you use Kaiba against him, because Kaiba's not afraid of showing all the money he spent on his Deck.
- Bastion starts to really doubt himself and creates his new Yokai deck from the GX Manga in hopes of being remembered by everybody again. Beat him; and he'll wonder if he's really a failure.
- While Marik already was this to some degree in his home series, Duel Links somehow makes him even more of one from a plot standpoint due to his event storyline revolving around having all of his memories post-Character Development erased and forcibly reverted to his Battle City-era personality.
- Woolseyism: The Standard Duelists in the Japanese version had generic names such as "Student who likes Dueling" or "Energetic boy." They were given proper names for the International release, which made them stand out as distinct characters, particularly when they started participating in event skits.
