Yugi Muto has defeated Mai Valentine and will be Dueling the winner of the next Duel , Joey Wheeler vs . Bandit Keith . When Croquet asks both contestants to show their tournament entry cards , Keith shows the one he took from Joey . So naturally , when Joey reaches for his , he can ' t find it . He has five minutes to find that card or he will be disqualified . Joey searches all over his room for it , but to no avail . He is just about to give up when Mai comes in and gives him her card . He arrives at the Dueling Arena just in the nick of time and presents Mai ' s card , to Keith ' s shock . The Duel between Joey and Bandit Keith begins , and Keith is revealed to be using a Machine - Type Deck . Unknown to Joey , Keith ' s Machine monsters are immune to non - physical attacks , and when Joey ' s first attack fails due to this , he is left exposed and takes damage . Keith lures him into opening his defenses again by moving to Set a monster and " accidentally " dropping it . Joey recognizes it as a non - Machine and seizes the opportunity for a powerful magical attack , but Yugi and Bakura realize that the monster , " Zoa " , has ATK that is not only higher than its DEF , but also higher than the ATK of any other monster on the field . The only reason to Set a monster like that in Defense Position is as a lure . But it is too late to warn Joey , who falls into the trap and takes heavy damage . Just as Keith prepares to deliver the final blow , his attack gets stopped , and everyone is thunderstruck to see that Joey also had a trap and just knocked out the strongest monster on Keith ' s field . On his next turn , Joey sets another card and announces that it is a Trap Card . He also begins a counterattack and taunts Keith in his inimitably grating fashion . Enraged at Joey ' s mockery and presumption , Keith attacks , but it wasn ' t a bluff , and it costs him the last monster on his field . With a handful of low - Level monsters and his own Dueling style , Joey has turned the Duel into a neck - to - neck battle , but Keith knows that this Duel is far from over . Will Joey defeat Keith and his mighty Machine monsters , or will he be eliminated and lose his chance to save his sister , Serenity Wheeler ? Featured Duel : Joey Wheeler vs . Bandit Keith .
