Yu - Gi - Oh ! 5D ' s - Episode 121 " The Miraculous Trump Card , Zushin the Sleeping Giant ! " is the one hundred - and - twenty - first episode of the " Yu - Gi - Oh ! 5D ' s " anime . It first aired in Japan on August 4 , 2010 . Summary . Yusei realizes the aim of Team Taiyo isn ' t to stall until they can burn away all their opponent ' s Life Points — it ' s actually to bring out " Zushin the Sleeping Giant " ! No one has ever thought this possible because it can ' t be summoned except by Tributing a Level 1 Normal Monster that has been on the field for 10 of each player ' s turn s — 20 turns in all . With a rush of fear , the crew realizes that " Key Mace " has been in play nearly that long already . Leo immediately sets up a sign , warning Crow that " Zushin the Sleeping Giant " is on the way . Once Crow gets over his disbelief at such an unexpected plan , he realizes he must destroy " Key Mace " immediately . However , Crow isn ' t the only one to see the sign . Taro realizes that Team 5D ' s has finally figured it out , and the fans doubt that Team Taiyo could really manage such a difficult Summon . The members of Team Ragnarok , who are watching the Duel ' s broadcast , pay closer attention at this development . The MC announces that " Zushin the Sleeping Giant " has never been Summoned before , and Team Taiyo only needs to survive one more turn from Team 5D ' s before the conditions are set . Taro reflects that " Zushin the Sleeping Giant " isn ' t a rare card , and yet it has power to rival the three Egyptian God Cards , but no one uses it because its conditions were too much of a weakness . But for a team that doesn ' t have any rare cards , that ' s the card they ' ll rely on . In fact , he figures that it ' s because they have no rare cards that they ' ve found the belief that they can call it out . He and his friends combined their strengths , and they had to endure painful Duels to get to this point , and he won ' t let them down . At the prospect of seeing such a card , the crowd becomes excited , and in unison , they begin cheering for " Zushin the Sleeping Giant " and for Team Taiyo . Team 5D ' s is stunned by the reversal of the audience against them , Team Ragnarok is impressed , and Jinbei sits in awe as Yoshizo smiles to see that the crowd was booing them all this time , and now they ' re cheering for them . Crow attempts to destroy the " Key Mace " , but a couple of traps from Taro shut him down . Furious that he ' s failed , Crow ends his turn . Taro rejoices that they ' ve actually managed it , and his friends cheer for him to show the crowd how they Duel . On their 10th turn , Taro successfully Tributes " Key Mace " to summon their ace monster , " Zushin the Sleeping Giant " . The MC and the crowd go wild , and Yusei realizes that they must now fight a Duel that has never been fought before . Taro targets " Black - Winged Dragon " for an attack , and the effect of " Zushin the Sleeping Giant " turns its ATK from 0 into the total of the opposing monster ' s ATK plus 1000 . This takes Crow very near to defeat , but then Taro activates a Trap to finish the job . Crow realizes this is as far as he goes , so in order to help Yusei as much as he can , he activates the Continuous Trap Card " Monster Baton " , which was Set by Jack , discard ing " Blackwing - Boreas the Sharp " to let Yusei use the effect later . The damage hits home , and Crow is defeated . Back in the pit , Leo transfers the trap to Yusei while Crow apologizes that he couldn ' t stop the summon of " Zushin the Sleeping Giant " . Yusei just smiles and says not to worry about it . When Jack asks if he really believes he can win , Yusei answers that he doesn ' t know , but he ' s having fun . He races out to catch up with Taro and " Zushin " , complimenting Taro on having such a great strategy . Taro answers that he is honored to be complimented by Yusei , who adds that Taro shouldn ' t hold back . Taro agrees , and Yusei realizes that Team Taiyo is of the same heart as he was back when he and his friends lived in Satellite . They had to see with all their potential , fending off the fear . In the same way , Team Taiyo is making the impossible possible . With all his heart , he takes his first turn , and by relying on his draws , he puts together a swarm of four monsters that allow him to Synchro Summon " Stardust Dragon " right away . With the two ace monsters already facing each other , the true Duel between Team Taiyo and Team 5D ' s is finally joined . Featured Duels . Crow Hogan vs . Taro Yamashita .
