History Tabletopgame / YuGiOh

* MasterOfIllusion: The Illusion type is inspired by phantasmal entities and magic used in the early manga that have powers outside the realm of conventional magic, such as reality magic and hypnotism. Illusion monsters have a shared card effect that prevents them from being destroyed by battle by an opponent's monster or destroy an opponent's monster by battle.

** Most cards that only gain Life Points are deemed useless as they merely delay the inevitable without affecting the board state (i.e. attempt to add to what the player has on field or in hand, or disrupt what the opponent has). However, tournament rules keep matches to a maximum of 40 minutes, and if that time limit is reached, the game goes into a 5-turn overtime, and a win is issued to the player with the higher LP at the end of that overtime. In that context, LP gain cards can suddenly help decide between a win or loss.

* MasterOfIllusion: The Illusionist type is inspired by phantasmal entities and magic used in the early manga that have powers outside the realm of conventional magic, such as reality magic and hypnotism. Illusionist monsters have a shared card effect that prevents them from being destroyed by battle by an opponent's monster or destroy an opponent's monster by battle.

XMeetsY: the "Kozmo" set is a fusion of ''Literature/TheWizardOfOz'' with ''Franchise/StarWars''

** [[https://yugipedia.com/wiki/The_Sanctuary_in_the_Sky The Sanctuary in the Sky]] field spell eventually got a few support cards that take this form called [[https://yugipedia.com/wiki/The_Fountain_in_the_Sky The Fountain in the Sky]] and [[https://yugipedia.com/wiki/The_Sacred_Waters_in_the_Sky The Sacred Waters in the Sky.]] The first lets the player remove destroyed LIGHT monsters in their GY from play to gain LP equal to the destroyed monsters ATK while the second lets them search out cards related to the Sanctuary in the Sky and gain 500 LP for each [[https://yugipedia.com/wiki/Hyperion Hyperion]] and [[https://yugipedia.com/wiki/The_Agent The Agent]] cards they have.

* HealingHerb: There's an old generic healing spell called [[https://yugipedia.com/wiki/Goblin%27s_Secret_Remedy Goblin's Secret Remedy that comes in this particular flavor. It restores 600 LP and does nothing else, making it outdated even at the beginning of the game due to flat out better healing spells already existing by the time it was printed.

** [[https://yugipedia.com/wiki/Red_Medicine Red medicine.]] It's a glass contained filled with [[ExactlyWhatItSaysOnTheTin red liquid]] that grants the player 500 LP.

** [[https://yugipedia.com/wiki/Poison_of_the_Old_Man Poison of the Old Man.]] A card depicting an old man holding two bubbling, smoking vials filled with green and purple liquid. One is a healing potion while the other is a deadly poison. Gives the player a choice between a 1200 LP gain for themselves or 800 points of direct damage to the opponent. It was also a quick play spell, which gave it some decent versatility for the time it was released in.

** Likewise, [[http://yugipedia.com/wiki/Tactical_Espionage_Expert Tactical Espionage Expert]] is quite deliberately [[Franchise/MetalGear Solid Snake]] in all but name.

** [[http://yugipedia.com/wiki/Super_Vehicroid_-_Stealth_Union Super Vehicroid - Stealth Union]] is based on the ''Anime/GaoGaiGar'', being made of an express train, a drill robot, and a stealth fighter. The anime makes this even more obvious [[https://youtu.be/9Y4FqDcz9dM?&t=1122 when it's combined with Super Conductor Tyranno]], as the latter's head takes the place of [[GaiGar]]'s lion head.

In 2020, Konami released '''''TabletopGame/YuGiOhRushDuel''''' alongside the anime ''Anime/YuGiOhSEVENS''. ''Rush Duel'', though sometimes described as a format, is technically a distinct card game with mechanics strongly derived from ''Yu-Gi-Oh!'' but incompatible with it. ''Rush Duel'' is currently exclusive to Japan and Korea.

* AntiFrustrationFeatures: Unlike the main TCG, the TCG-exclusive Speed Duel boxes are comprised largely of fixed, non-randomized pre-built decks, making it extremely cheap and easy to get into the format relative to other card games. The only randomized product is a pack of all Secret Rares that comes with every box, which tends to feature powerful cards or staple cards. The Speed Duel boxes also offer the chance to reprint old cards that Konami would otherwise have no reason to reprint, making it much easier for players of legacy formats such as Edison who struggle to obtain cards that have historically had limited prints.

The concept of the card game first appeared in the ''Manga/YuGiOh'' manga as an {{homage}} to ''TabletopGame/MagicTheGathering'', of which author Creator/KazukiTakahashi is a fan. Originally, the manga was intended to feature a new game every few weeks, with the card game (then known in-universe as ''Magic & Wizards'') being one of many. However, Takahashi received large amounts of fan response immediately after the card game debuted in the manga, who wanted to know more about the game. Takahashi in response reworked the manga storyline to more prominently feature the card game, and gradually developed its game mechanics, which are loosely based on that of ''Magic'', which [[NewRulesAsThePlotDemands generally]] agreed with how the characters played.

*** Vampire Retainer may be a wolf, but its normal white right half and deranged black left half, with jagged teeth and flaming red eye, bring to mind [[Franchise/{{Danganronpa}} Monokuma]].

** "Properly summoned". Long story short, if a monster that cannot be Normal Summoned/Set (such as nearly every Extra Deck monster, or anything that has the "Cannot be Normal Summoned/Set" or "Must first be Special Summoned" clause) finds its way into the Graveyard or banished in any way other than being sent there after being summoned via its correct summoning procedure, it cannot be Special Summoned to the field under any circumstances, even overriding the "ignoring its Summoning conditions" clause. This even includes monsters that were properly summoned then sent to the Graveyard/banished then summoned back to the field, as once they return in this way they lose their "properly summoned" flag and cannot be brought back a second time. This is an integral rule to the modern card game but is rarely touched upon by rulebooks, causing many beginner players to wonder why they can't summon back a Fusion/Synchro/Xyz/Link Monster that they dumped to the Graveyard from their Extra Deck.

** The idea behind monster Attributes.
** The specialty of the [[http://yugipedia.com/wiki/Charmers Charmer]] Archetype.
** As the name itself implies, the "Elemental HERO" archetype, down to the point of every basic Elemental HERO being able to fuse with practically any other, except Neos, which has its own flock of Aliens to fuse with.

** And the other way around works, too. Check out the Silent Swordsman and Silent Magician. Now look at Kargan Dragonlord and Guul Draz Assassin... and Chandra Nalaar's Japanese Duel Deck art.

''Yu-Gi-Oh!'' has different names and administration structures in different territories. The so-called ''Official Card Game'', or OCG, has been handled by Konami since the beginning; it administers East Asia. The other administration setup, called the '''''Yu-Gi-Oh! Trading Card Game''''', or TCG, was originally manufactured and distributed by Upper Deck Entertainment, at Konami's own behest, throughout the remaining territories worldwide. However, in 2008, UDE lost the license amid some allegations of wrongdoing, and now the TCG is administered by Konami as well. The game is mostly identical on each side of the Pacific; the only differences are that some cards that debut under one administration do not appear in the other for a good, long while, if ever; there are some difference about the Damage Step rules; the Forbidden/Limited lists on each side differentiates since September 2013; and, Konami alters some card artwork to prevent incidents with MoralGuardians.

*** Interrupted Kaiju Slumber is a Spell Card that destroys all monsters on the field, then Special Summons two "Kaiju" monsters with different names, one to each side of the field. For the 99% of other cards in the game, to Summon a monster or activate and resolve an effect that Summons a monster, you must be able to meet the conditions of Summoning throughout the process of Summoning, which is why you cannot do things like Special Summon a Warrior monster from your Extra Deck by using a Warrior you control as material while "There Can Be Only One" is face-up on the field. "Kaiju" monsters have a conditional effect that states that each player can only control one "Kaiju" monster, so theoretically "Interrupted Kaiju Slumber" cannot be activated while either player controls a "Kaiju". However, Konami has stated that you can in fact play "Interrupted Kaiju Slumber" while either player controls a "Kaiju", on the basis that "then" is conjunction used between the effect that destroys and the effect that Special Summons, meaning that they do not occur with the same timing.

** The flavor text of Normal Monsters printed in the later years of the card game lampshade their worthlessness when compared to Effect Monsters. Examples include [[http://yugipedia.com/wiki/Rabidragon Rabidragon]], [[http://yugipedia.com/wiki/Wattaildragon Wattaildragon]], and [[http://yugipedia.com/wiki/Alligator%27s_Sword Alligator's Sword]].

The card art in ''Yu-Gi-Oh!'', despite lacking one central setting, are known to have featured complete storylines with background lore, recurring characters, and even chronological events. These stories are termed "metaplots" here, and can be found [[Metaplot/YuGiOh here]]. The character and gameplay details of individual archetypes and series can be found on [[Characters.YuGiOhCardGame this Character Sheets page]]. Subjective tropes can be found [[YMMV/YuGiOhCardGame here.]] Trivia can be found [[Trivia/YuGiOhCardGame here.]]

** Now that there are thousands of individual cards in the game ''(with updated rulings, to boot,)'' keeping track of these can be a pain. Fortunately, there are official tournament judges and [[TheWikiRule even a wiki]] to help with this, but there are some things that will not be immediately obvious to a player that requires him to double check from an official source to confirm it. For example: Cards like Axe of Despair and [[ShockAndAwe Summoned Skull]] are now considered to be "Archfiend" cards ''(the newer prints even say so on them)''. If you had the old versions of these cards, how were you supposed to know?
