A four-way free-for-all Duel to determine the Battle City tournament Semi-Final pairings. The first two duelists to lose will face each other in the first Semi-Final. The two winners will face each other in the second Semi-Final. This allows each duelist to influence who he will face next by deciding to attack who at what time.
Kaiba wants to duel Yugi so that, when he wins, he will have two Egyptian God Cards, as he knows he will need all the power he can get to stand up against The Winged Dragon of Ra.
Yugi at first cannot decide who he wishes to face due to having reasons to fight everyone: Kaiba to settle their rivalry, Marik to defeat him and save the world and Joey, to keep his promise about dueling him in the finals, so he decides to wait and see what he will do.
Joey wants to duel Marik so he can win back Mai's soul and claim revenge for her capture.
Marik doesn't really care who he faces or when, so he just plans to have fun wreaking as much havoc in this duel as possible.
Each Duelist must play with no more than 40 cards in his Deck.
Each Duelist can attack or target any of the other three, but may not attack until one full turn has been played.
As each player's Life Points decrease, their chair in the Duel Tower rises up. When a player's LP reach 0 their chair will rise all the way to the top, i.e. the setting for the Semi-Final round.
Turn 5: Kaiba
Kaiba draws. Kaiba's hand contains "Ring of Defense", "Ring of Destruction", "Blue-Eyes White Dragon", "Pot of Greed", and "Shrink". "Vorse Raider" attacks Joey directly, but Yugi activates his face-down "The Regulation of Tribe" by declaring "Beast-Warrior" for its effect. As a result, "Vorse Raider" can't attack while "The Regulation of Tribe" is face-up. Also during each of Yugi's Standby Phases, he must Tribute one monster to keep "The Regulation of Tribe" on the field or else it will be destroyed.
