Paradox-Billiards-Vostroyan-Roulette-Fourth-Dimensional-Hypercube-Chess-Strip Poker

Paradox-Billiards-Vostroyan-Roulette-Fourth Dimensional-Hypercube-Chess-Strip Poker is the name given in the 41st millennium to Yu-Gi-Oh!, and is the card game of choice for both The Emperor and Tzeentch. Other known players are Kitten, Cegorach, The Deceiver, and Creed.

Because of its overly long name, it is sometimes simply referred to as "a Children's Card Game." Both The Emperor and Tzeentch can pull opponents into the Warp and host an "Ultra-Game," where the loser is exiled to Ultramar - which according to the Deceiver "flippin' sucks".

Player Decks

 * The Emperor uses an overpowered and highly optimized deck that allows him to maximize buffs on his first turn. He even possesses one of the Egyptian God cards, the Winged Dragon of Ra - or as he calls it, "Mega Ultra Chicken." However, he is able to use a card combo to mutate it into an even more powerful monster that highly res embles Sanguinius called "The Winged Warrior of Terra". This deck build comes at the cost of most of his life points, which makes him easy to defeat if one can counter his various buffs and spell cards.
 * Kitten uses a fairly mundane deck of cards with various defensive spells and average monsters. Most, if not all, of his monsters, are cat-themed or beast-themed. He is able to defeat both Tzeentch and The Emperor by reversing their overpowered spells and using his ace monster, Wind-Up Kitten to clear the board of his opponents' own sole ace monsters, then attacking them conventionally.
 * Tzeentch 's deck is almost entirely made of spell cards and trap cards, with only one monster - and virtually all of these are banned from real-world tournament lists. His strategy is to use Morphing Jar #2 to dispose of most of his cards in the graveyard in order to power up Magical Explosion, killing the enemy player outright without needing to use monsters. Tzeentch claims that he's able to plan for every possibility, but in reality, he can read his opponent's thoughts and simply counters whatever they have in their hand. He is defeated when Kitten is able to pull Morphing Jar #2 off the field long enough to send his Beast monsters to defeat Tzeentch.
 * Asdrubael Vect played Skull Servant and King of Skull Servants alongside three copies of Foolish Burial during his game with the Fyodperor, suggesting he uses a Skull Servant/Wright deck and powers up his King of Skull Servants by sending other Skull Servant/Wright cards to the graveyard with Foolish Burial. Though his initial strategy is to "sandbag" (a reference to a play style in the Super Smash Brothers series where players deliberately play badly, named after the inanimate but presumably living sandbag first seen in the Home Run mode) by pretending he doesn't know the rules to lower his opponent's guard.
 * While Fyodperor 's cards are completely unseen, it can be assumed that he was characteristically going easy on Vect as his face-down card was destroyed by a normal Skull Servant, which is notoriously weak (even by the standards of when it was first released) and only has 300 attack points and he had no other cards on the field in spite of Vect having been "sandbagging" himself up until that point.
 * Cegorach 's deck wasn't revealed due to Magnus destroying it before they could play. Due to him calling it a "gimmick deck," it is more than likely his cards were all mostly clown-themed.
 * While Ma gnus didn't play, it can be assumed that if he did, he would likely use a combination of control and beatdown cards with a focus on hand traps, normal spells, and quick-play spells as he mentions he plays "Red/Blue" (also known as Izzet) in Magic the Gathering and he made a pun regarding "hand traps" when he used an explosive bear trap to destroy Ceogarch's duel disk.

Trivia

 * Alfabusa has suggested that the real reason that Kitten is winning every duel is that he's using a deck based on the anime and not the real world card game. This was pointed out with how he uses the anime version of Rescue Cat.
 * Even in the anime, Mystical Space Typhoon does not actually negate the activation of the destroyed card unless it's a continuous spell, trap, or field spell and it doesn't have a trigger or ignition effect. This is a common misconception among people who don't actually read the card's effect when playing it. This means Kitten only beat Tzeentch by no one actually properly knowing the rules.
 * Another example of anime-version use is the Emperor's Golden Castle of Stromberg, as it's anime version is incredibly overpowered compared to its TCG version.
 * Many of the jokes, including referring to the game as “a Children’s Card Game,” are derived from the show Yu-Gi-Oh Abridged .
 * "Mega Ultra Chicken" in particular a reference to a former reoccurring joke in Yu-Gi-Oh!: The Abridged Series where Winged Dragon of Ra is called as such in reference to the Aqua Teen Hunger Force episode Video Ouija.
 * The line "The legends are true" also references how after mentioning Mega Ultra Chicken the character Billywitchdoctor.com shushes the characters and says "He is legend."
 * The "Ultra Game" joke is a reference to the recurring "Shadow Games" in the Yu-Gi-Oh! franchise, wherein the dub of the anime the loser would sometimes be banished to the "Shadow Realm", which was 4kids' attempt at censoring the themes of death.
 * The game's name is a mixture of various other board games, among them is 'Vostroyan Roulette'. Vostroya is a planet in Segmentum Obscurus with an aesthetic based on 18th century Russia. As such, Vostroyan Roulette can be seen as the 40k equivalent of Russian Roulette.
 * Hypercubes are four (or higher) dimensional objects that are analogs of squares, such as the hypothetical fourth-dimensional tesseract. In Warhammer 40K, tesseracts are associated with the C'tan and Necrons, with the existence of the Tesseract Vault and the Tesseract Labyrinth.
