Sylvio Normal Summons "Kama 1" (Yosen Counter 1 → 2), activating its effect to Normal Summon "Kama 2" ( Yosen Counter 2 → 3), and also activating the latter's effect to Normal Summon "Kama 3" (Yosen Counter 3 → 4). The effect of "Kama 2" lets it attack Yuya directly by halving the battle damage it inflicts. Yuya attempts to get an Action Card, but is intercepted by the attack of "Kama 2" (Yuya 3100 → 2200). He activates the effect of "Kama 3" again, adding "[[Yosenju Shinchu L (anime)|Yosenju Shinchu L]]" from his Deck to his hand. He then activates the effect of "Training Grounds", removing 3 Yosen Counters (Yosen Counter 4 → 1) to add "[[Yosenju Shinchu R (anime)|Yosenju Shinchu R]]" from his Deck to his hand. Sylvio activates "Shinchu L" ({{Rightpendulum}} 3) and "Shinchu R" ({{Leftpendulum}} 5) in his [[Pendulum Zone]]s. He then activates the effect of "Shinchu R"; since he has a "Yosenju" card in his other Pendulum Zone, he increases its [[Pendulum Scale]] to 11 ("Shinchu R": {{Leftpendulum}} 5 → 11) until the End Phase, though he can only Special Summon "Yosenju" monsters this turn. Sylvio Pendulum Summons "Mayosenju Daibak" (3000/300) (Yosen Counter 1 → 2). He activates its effect, letting him return up to two cards on the field to the owner's hand. He targets "Timegazer" and "Stargazer", but before the effect [[resolve]]s, since he controls "Daibak", he activates his face-down "[[Dizzying Winds of Yosen Village (anime)|Dizzying Winds of Yosen Village]]". When a non-"Yosenju" card would return from the field to the hand, it's [[shuffle]]d into the Deck instead. Both cards [[resolve]], thus "Timegazer" and "Stargazer" are shuffled into Yuya's Deck. Sylvio activates "[[Yosen Whirlwind (anime)|Yosen Whirlwind]]" by [[pay]]ing 800 [[Life Points]] (Sylvio 2800 → 2000).  At the End Phase, "Kama 1", "Kama 2" and "Kama 3" return to the hand, triggering the effect of "Yosen Whirlwind", which lets Sylvio return a card from the field to the hand every time a "Yosenju" monster he controls returns to the hand. Since three "Yosenju" returned to the hand, he chooses to return Yuya's "Kaleidoscorp", "Pinch Helper" and "Drummerilla", and due to "Dizzying Winds", they are shuffled into the Deck instead. The effect of "Daibak" activates, returning itself to the hand since it was Special Summoned this turn, and thanks to "Whirlwind" and "Dizzying Winds", Sylvio shuffles "Odd-Eyes" into Yuya's Deck. In addition, the Pendulum Effect of "Shinchu R" expires ("Shinchu R": {{Leftpendulum}} 11 → 5).
