* AdaptationalSuperpowerChange: Or Adaptational Deck Change, regarding a number of characters such as[[Anime/YuGiOh Valon]]. In the anime proper, he uses an Armor deck; since those cards don't actually exist, he instead uses a Deskbot deck. In addition, [[Anime/YuGiOhVRAINS]] uses an Aroma deck as the Sunvine/Sunavalon archetypes had not yet been released in the real life card game.

** In the "Duel Monsters" Campaign, there's no Millennium arc as the last fight before the Ceremonial Duel is against Dartz, who is the final boss in Season four of the show. Understandably, it's cut out since the entire season is an RPG-Esque battle instead of card duels.

** If you are using magic/trap cards that punish your opponent for certain plays, the computer will STILL perform said plays, even if they lose the duel in doing so. One of the arguably best examples(which can be observed as early as the reverse version of the Yami vs Bakura duel in campaign) is if they are below 1000 LP and decide to send several monsters to graveyard(be it by fusion summon or tribute summon, for example) while you have multiple coffin sellers active, which deal 300 damage each whenever your opponent sends a monster to the graveyard. Any sane player would try to get rid of the traps first before trying to send more cards to the graveyard, but the AI will [[TooDumbToLive happly kill itself in such scenario]].

** The AI prioritizes using searching cards to thin the deck out, rather than using them to find important cards. This is most notable with Pegasus in the GX story, as his Toon deck has three copies of Toon Table of Contents, which he uses to...search the other two copies out, before using it to search an important card like Toon Kingdom. Crowler, his opponent, has plenty of removal, so the absence of two additional search cards greatly hurts the possibility of him being able to get his many Toon cards online.

** The most [[{{Pun}} painful]] example of this involves Painful Choice, four random magic cards, and one Exodia piece as the options. The AI will '''[[TooDumbToLive always]]''' choose the Exodia piece. Bonus points if it was the last piece you needed to win the duel.
*** And speaking of Painful Choice, the AI would always choose the monster card with the Highest Attack value out of the five thus toolbox the card into a searcher as well as graveyard setup. In one of many possible examples, Painful Choice becomes a searcher for Grinder Golem (a banned card infamous for token generation, has 3000 ATK), and if the other options include Level Eater (600 ATK), Dandylion (300 ATK), and Orcust Harp Horror (1700 ATK and here's the problem, all are also banned cards known for mass summoning and token generation whose effects work in the graveyard and/or activate when sent to the graveyard), the AI [[TooDumbToLive deserves that defeat]]. Or in a Pendulum Magician deck, it could be used to search out Astrograph Sorcerer (2500 ATK), and send Double Iris (1500 ATK), Purple Poison (1200 ATK), White Wing (1600 ATK), and Black Fang (1700 ATK) Magicians to the Graveyard. As soon as Astrograph Sorcerer hits the field (incredibly easy because of its special summoning condition or by Pendulum Summon the card), you can summon Supreme King Z-ARC via Astrograph Sorcerer's effect because the aforementioned Magicians are treated as the Pendulum, Fusion, Synchro, and XYZ dragons respectively and this works when the cards are on the field, hand, and/or in the graveyard; all because the AI chose the highest ATK monster Astrograph Sorcerer [[TooDumbToLive to your hand]].

* LoadsAndLoadsOfCharacters: The game features over one hundred characters all over the six animated series.

On April 25, 2019, An UpdatedRerelease named ''Yu-Gi-Oh! Legacy of the Duelist: Link Evolution'' was released exclusively for the ''UsefulNotes/NintendoSwitch'' in Japan, but eventually made its way to the USA and Europe on August 20, 2019. Playstation 4, Xbox One, and PC received the game later on March 24, 2020. This version of the game includes a Campaign Mode for ''Anime/YuGiOhVRAINS'', as well as the Master Rule 4 update to the real card game's rules. It also included all content from the original ''Legacy of the Duelist'' that was once DLC, with updated Campaign Mode cut scenes to boot.

** The AI loves to put cards in defense position when you have monsters like Blue Eyes Chaos Max Dragon on the field, often getting themselves OTK'd thanks to this.

*** The one exception to this is Jesse. The AI will always try to send his Crystal Beasts into the backrow whenever possible, until it gets completely clogged. On paper, that is a good strategy because his field spell, Ancient City - Rainbow Ruins, gains increasingly powerful effects for each one, and if the backrow is full can summon a monster from there each turn, and if it happens to be Ruby Carbuncle it will result in a massive advantage. However, the AI will NEVER use said final effect, thus locking himself out of all the spell and trap cards on his deck; most importantly blocking his main win conditions, Dark Hole and Crystal Abundance.

However, the AI will NEVER use said effect, not even with Ruby as one of the potential targets.
