History Trivia / YuGiOhCardGame

** For the game's 25th anniversary, two cards, "Magician of Bonds and Unity" and "Dragon of Pride and Soul", were released into Core Boosters as special promo cards that are relatively hard to pull. They have 2500 ATK/DEF, require one player to have 25 or more cards in their Graveyard and get an additional 2500 ATK/DEF bonus when another player has 25 or more cards in their Graveyard.

* MilestoneCelebration: Ten Thousand Dragon was created to celebrate the number of cards in the game reaching the 10,000th mark. To Special Summon it, the controller must Tribute monsters they control whose combined ATK and DEF is at least 10,000. If summoned this way, its ATK and DEF then [[ExactlyWhatItSaysOnTheTin become 10,000]].

* ExecutiveMeddling: The reason why Creator/{{Konami}} can't hold prize money for their tournaments is because of this trope. Kazuki Takahashi, creator and rights holder to the franchise, forbid Konami from holding prizes for their tournament since he wanted the game to be for kids, and that holding prize money for it would "be too much like gambling" in his opinion.

** And for Blue-Eyes Ultimate Dragon, we have Cyber End Dragon, Borrelend Dragon, and Neo Galaxy-Eyes Photon Dragon. (Though the latter differs in that it is a triple Level 8 material Xyz monster.) One can think of Red Nova Dragon as a Expy to [=BEUD=] as well considering that just to summon Red Nova takes two Tuners, meaning he usually has 4500 or more attack.

** A member of the TCG community known as "[=Payne96=]" made a countdown until Konami made new Volcanic cards. Five years after they started, Volcanic gained support with the article announcing that it came after five years of ''pain''.

** [[https://yugioh.fandom.com/wiki/Shuttleroid Shuttleroid]] a -roid monster that was released in 2007 in the OCG and has never been released in the TCG, for unknown reason.

** There are a naive few who believe that cards showed in the show are the same as they are in real life. This is actually rarely the case. Usually, most cards that do pop up in the show are often rebalanced when introduced to the game, either through buffing it or nerfing it depending on the effect. In the cases where they ''are'' kept remotely similar with a few minor differences, it often causes a lot of disputes when it comes to the exact rulings of how the effects work and interact. There are even cases where the card ends up being completely different than in the anime/manga.
** In the early days of the game, a lot of people (mostly kids) did not know that tribute summons were a thing. This is mainly due to their first experience with the game as the anime, where it's not until Battle City where the idea that you had to tribute lower level monsters came into play. Similarly, a lot of kids thought you started at 2000 or 4000 life points; the original series never really shook this off even in the later seasons.
** Another common mistake is believing that you can Normal Summon (face-up) a monster in Defense Position, since the anime characters have been shown doing it multiple times. This is actually not how the card game works, and the incorrect belief ends up so prevalent in the card game fandom (particularly among kids and newbies) that anime characters Normal Summoning in Defense Position no longer happens from ZEXAL series onward.

** There were several toy Duel Disks released by Konami and Mattel during the early [=2000's=] while the first few anime series were airing. These tended to be AwesomeButImpractical since they were not exactly designed with functionality in mind, but could be played with if you really, ''really'' wanted to (and didn't mind damaging your cards one way or another). Among other models, there were the iconic Battle City Duel Disk, the Chaos Duel Disk from the Doma Arc, the Academy Duel Disk from ''GX'', and Yusei's Duel Disk, which is an updated model of the Battle City version. Following this, Konami and Mattel largely ceased production of the toy Duel Disks, but Konami would later bring it back for ''SEVENS'' with a functional replica of Yuga Ohdo's Duel Disk.
