" Different Dimension Dragon " destroys Dartz ' s " Orichalcos Malevolence " , but Dartz receives no Battle Damage due to the effect of " Orichalcos Kyutora " . The four " Mirror Knight Token s " attack Yami Yugi directly ( Yami Yugi 3500 → 3000 → 2500 → 2000 → 1500 ) . Dartz then Set s a Card . On Dartz ' s End Phase , the effect of " Ambush Shield " expires ( " Different Dimension Dragon " : 4000 → 1400 / 1500 ) Turn 22 : Kaiba Kaiba draws " The Fang of Critias " and subsequently activates it , to fuse the former with Yami Yugi ' s Set " Mirror Force " and Special Summon " Mirror Force Dragon " ( 2800 / 2800 ) in Attack Position . " Mirror Force Dragon " attacks " Mirror Knight Pegasus " . The effect of " Mirror Knight Pegasus " activates ( " Mirror Knight Pegasus " : 500 → 2800 / 0 ) . Dartz then destroys the Shield Counter on " Mirror Knight Pegasus " to prevent his own destruction . The effect of " Mirror Force Dragon " then activates , inflicting Battle Damage equal to the difference between the ATK of " Mirror Force Dragon " and the total ATK of his monsters that had less ATK than " Mirror Force Dragon " at the start of the Damage Step . Due to the effect of " Orichalcos Kyutora " , Dartz takes no Battle Damage . After that happens , the last effect of " Mirror Force Dragon " activates , destroying all of Dartz ' s monsters without applying damage calculation . ( At this point , Yami Yugi and Kaiba find out that the souls of their friends were released upon being destroyed in Mirror Knight form and are now safe . ) Since " Orichalcos Kyutora " was destroyed , its final effect activates , allowing Dartz to Special Summon " Orichalcos Shunoros " in Attack Position ( ? / 0 ) , " Orichalcos Dexia " ( 0 → 500 / 0 ) in Attack Position and " Orichalcos Aristeros " ( 0 → 500 / 0 ) in Defense Position . The ATK and DEF of " Orichalcos Shunoros " are equal to the total amount of Damage Negated by the effect of " Orichalcos Kyutora " ( " Orichalcos Shunoros " : ? → 19500 → 20000 / 0 → 19500 ) ( NOTE : To see how this result is achieved , see Damage Prevention Table in the NOTES section below ) . Dartz places " Orichalcos Shunoros " in his Spell & Trap Card Zone ( back row ) and " Orichalcos Dexia " and " Orichalcos Aristeros " in his Monster Card Zone ( front row ) . This means that as long as " Orichalcos Dexia " and " Orichalcos Aristeros " exist on the field , " Orichalcos Shunoros " cannot be Attack ed . As a monster he controlled was destroyed , Dartz activates his face - down " Martyr Curse " to force " Mirror Force Dragon " and " Orichalcos Shunoros " to battle . Due to the last effect of " Martyr Curse " , Seto cannot activate the effect of " Mirror Force Dragon " . " Orichalcos Shunoros " destroys " Mirror Force Dragon " ( Seto 600 → 0 ) . Since Seto has lost the Duel , his " Different Dimension Dragon " is destroyed . The third effect of " Orichalcos Shunoros " then activates , decreasing its ATK and DEF by the ATK of the monster it just battled ( " Orichalcos Shunoros " : 20000 → 17200 / 19500 → 16700 ) . Before his soul is taken away , Seto activates his face - down " Wish of Final Effort " to increase Yami Yugi ' s Life Points by the ATK of " Mirror Force Dragon " ( Yami Yugi 1500 → 4300 ) .
