S01E121: The Miraculous Trump Card - Sleeping Giant Zushin!

Yusei reveals that Taro's plan is to sacrifice a level 1 monster that has been on the field for ten of his turns so he can summon his trump card, Zushin the Sleeping Giant. When the crowd gets word of this, they start cheering for Team Taiyo, along with the people from their hometown. Crow's attempts to destroy the sacrifice fails, allowing Taro to summon out Zushin, which defeats Crow. Yusei takes over, and brings out Stardust Dragon to battle against Taro.
