Yu - Gi - Oh ! Duelist - Duel 168 " The Waiting Grave " , also known as " The Twilight Cemetery " in the Japanese version , is the 168th chapter of the " Yu - Gi - Oh ! Duelist " manga in the English version and the 227th chapter of " Yu - Gi - Oh ! " in the Japanese version . Summary . Kaiba ' s " Des Feral Imp " attacks Ishizu directly , reducing her Life Points to 2400 . Kaiba laughs to himself , thinking that the Egyptian God card " Obelisk " sleeps in his hand . When it awakes , Ishizu is finished . But Ishizu thinks that Kaiba is wrong . She has seen his future ; he will die by " Obelisk ' s " own hand , seeing " Obelisk " explode , and throwing Kaiba through the air in horror . On the sidelines , Jonouchi observes that Kaiba and Ishizu ' s Life Points are pretty close , commenting that Ishizu isn ' t bad . Dark Yugi states that Kaiba ' s strategy is to destroy this opponent ' s Deck . He has a Power Deck that crushes his enemy with high - Level monsters . Dark Yugi admits that he still isn ' t sure of Ishizu ' s strategy , but she must have one . Anzu remembers that in the beginning , Ishizu played that card that let her and Kaiba discard part of each other ' s hand , and then Kaiba played " Crush Card " on her , so she lost all of her best monsters . Jonouchi agrees that Kaiba ' s calling the shots , as all of Ishizu ' s best cards are in the Graveyard . She ' s putting up a good fight , but she ' s doomed . Dark Yugi suddenly seems to realise something . He wonders if she could be . . . while looking at Dark Marik , who has an air of confidence on his face . Dark Yugi thinks that if Marik and Ishizu are sister and brother , then they both carry the blood of Ishtar . Ishizu too , is a member of the clan of Tomb Guardians . Then he remembers that tombs are found in a " graveyard " , and he wonders if that is the keyword of Ishizu ' s Deck and her terrifying strategy . Kaiba thinks that now he ' ll drive Ishizu even farther into his trap , but Dark Marik laughs to himself , thinking that Kaiba ' s dug his own grave , and he ' ll suffer in it . Declaring that he ' ll show Ishizu the terror of Deck Destruction , Kaiba activates his Virus Card , " Virus Cannon . " Jonouchi is shocked that Kaiba had another Virus Card , and the cannon appears on the field , firing at Ishizu ' s Deck . Her Deck begins to smoke , and Kaiba laughs , telling Ishizu to choose ten Spell Card s and put them in the Graveyard . Ishizu does so , and Kaiba laughs , telling her to take that ; he Deck is dead . Ishizu replies that she had a vision that this would happen . Kaiba is furious that Ishizu is still putting up a bold front , and Ishizu adds that it is Kaiba who fell into a trap , the trap of the gravekeepers . She reveals it , activating her face - down card , " Exchange of the Spirit . " Kaiba is horrified , as the card forces the players to switch the cards in their Deck with those in their Graveyard ( at a cost of 1000 of Ishizu ' s Life Points , as well as her requiring at least 15 cards in her Graveyard ) . Ishizu confrims it . When this card is activated , the living will die and the dead will rise . The cards in Kaiba ' s Graveyard will return to life , and the cards in his Deck will go to their eternal rest . Dark Yugi thinks that it ' s unbelievable . So this is what Ishizu was aiming for . Kaiba ' s Graveyard only has a few minor cards , but Ishizu ' s Graveyard has her main cards which were wiped out by Kaiba ' s viruses . In other words , " Exchange of the Spirit " has broken the back of Kaiba ' s Deck , and Ishizu ' s Deck is good as new . Dark Marik thinks that it ' s " so scary , " and now Kaiba knows that it was his Deck that was destroyed . Kaiba ' s in shock - there were only six cards in his Graveyard ( " Kaiser Glider , " " Polymerization , " " Crush Card , " " Vorse Raider , " " Shrink , " and " Virus Cannon . " ) Meanwhile , Ishizu ' s Deck has all the cards he forced her to discard with his diseases , and most of them are her best cards . He looks at his six card Deck , thinking that all his plans are ruined . Ishizu states that it ' s her turn . Jonouchi states that Kaiba ' s dead ; there ' s no way out of Ishizu ' s trap . Anzu states that Ishizu really can see the future , otherwise Kaiba wouldn ' t have lost this easily . Ishizu Set s a card , and Kaiba refuses to accept it . It ' s not his future to lose . Ishizu Summons " Kelbek " and ends her turn . Kaiba draws , his old card , " Virus Cannon , " and Ishizu immediately activates her Trap Card , " Muko , " commenting that it seems Kaiba ' s card was short - lived . Kaiba discards his card , thinking that Ishizu knows all the cards in his Deck , and she knew Kaiba drew his Virus Card . Ishizu mentally agrees , thinking that next turn , when Kaiba draws " Crush Card , " she will force him to destroy it too . Kaiba doesn ' t attack , ending his turn . Jonouchi is surprised that Kaiba didn ' t attack , as his monster has more attack points . Ishizu thinks that she knows all and sees all . The only chance Kaiba has left is the " Soul Exchange " card in his hand . Kaiba ' s waiting for Ishizu to play three monsters , to use them as Tribute s to Summon the God . She thinks that Kaiba has not realised , as she Summons " Zolga , " that Kaiba ' s defeat is predestined . She thinks that it ' s over . Kaiba fumes to himself . Dark Yugi suddenly interrupts , telling Kaiba that he can see kaiba ' s future . He sees a battle waiting to be fought , he sees a road that goes as far as the eye can see . Battle City isn ' t over yet . It isn ' t over until Kaiba and Yugi fight . Kaiba laughs , telling Yugi to wait for him . Featured Duel : Seto Kaiba VS Ishizu Ishtar .
