[[Yusei Fudo|Yusei]] draws. He then Normal Summons "[[Max Warrior]]" (1800/800) in Attack Position. Yusei then attacks "[[Wise Core]]" with "[[Max Warrior]]". "[[Max Warrior]]'s" effect raises its ATK by 400 during the Damage Step only ("Max Warrior": 1800 → 2200/800). Ghost activates "[[Labyrinth of Kline]]", reducing the [[Battle Damage]] he takes to 0 and preventing "[[Wise Core]]" from being [[destroy]]ed. The original ATK and DEF of "Max Warrior" are then swapped until the next turn's End Phase ("Max Warrior": 2200 → 1200/800 → 1800). Since it is the end of the Damage Step, the effect of "Max Warrior" wears off, removing the 400 ATK boost that the effect of "Max Warrior" gave to itself ("Max Warrior": 1200 → 800/1800). Yusei then Special Summons "[[Turbo Booster]]" from his hand (0/0) in Attack Position via its own effect. Yusei then Tributes "Turbo Booster" to activates its effect, [[destroy]]ing "[[Wise Core]]". This activates "[[Wise Core]]'s" effect, allowing Ghost to Special Summon from his hand or Deck "[[Meklord Emperor Wisel|Meklord Emperor Wisel Infinity]]" (0/0) in Attack Position, "[[Wisel Top]]" (500/0) in Attack Position, "[[Wisel Attack]]" (1200/0) in Attack Position, "[[Wisel Guard]]" (0/1200) in Defense Position, and "[[Wisel Carrier]]" in Attack Position (800/600). Due to the effect of "Wisel Infinity", "Wisel Infinity's" ATK becomes equal to the combined ATK of all the other Wisel monsters that Ghost controls ("Meklord Emperor Wisel Infinity": 0 → 2500/0).
