He declared an attack on " Dark Magician " with " Basic Insect " . Dark Yugi laughed and said " you said attack " , a la how Haga had said it to Ryuzaki , during their National Championship Duel .

Haga Summoned " Larvae Moth " in Defense Mode in the Forest ( DEF : 400 → 520 ) . Dark Yugi ' s turn Seeing how weak " Larvae Moth " was , Dark Yugi suspected Haga was planning a combo attack and that his face - down was part of it . To avoid the risk of having all of his monsters destroyed , he used " Monster Recovery " to return all of them and his hand to his Deck and drew 5 new cards . He then Summoned " Kuriboh " ( ATK : 350 ) and attacked .

Haga ' s turn Haga passed . Dark Yugi ' s turn Jonouchi reminded Dark Yugi how important it was that he won and told him to burn down the Forest , if necessary to take out the cocoon . Mai Kujaku began to mock Dark Yugi ' s friends for thinking they could help him by cheering . Anzu disagreed , saying that Dark Yugi would hear their feelings and win . Mai was unconvinced , but noticed how confident Dark Yugi had suddenly become . Taking Jonouchi ' s advice about burning down the Forest , Dark Yugi Summoned " Curse of Dragon " and activated " Burning Land " , allowing " Curse of Dragon " to destroy the Forest terrain around " Cocoon of Evolution " , removing its Field Power Source ( " Cocoon of Evolution " : 2600 → 2000 DEF ) . He then attacked " Cocoon of Evolution " with " Gaia the Fierce Knight " . This destroyed the cocoon , but " Larvae Moth " had managed to evolve as far as " Great Moth " , which came out of the cocoon . Haga ' s turn Haga got " Great Moth " to take flight , making it immune to any ground based attacks . Dark Yugi ' s turn Dark Yugi used " Polymerization " to fuse " Gaia the Fierce Knight " with " Curse of Dragon " , creating " Gaia the Dragon Champion " , which could fly and equaled " Great Moth " in terms of ATK . Haga ' s turn Haga got " Great Moth " to attack all of Dark Yugi ' s landbound monsters . This destroyed " Beaver Warrior " ( Dark Yugi : 750 → 600 Life Points ) . He had not noticed that Dark Yugi fused " Gaia " with " Curse of Dragon " and expected it to be destroyed too . Although it was not destroyed , " Gaia " had become infected by the poisonous pollen from the attack , reducing its ATK ( " Gaia the Dragon Champion " : 2600 → 2100 ATK ) . Dark Yugi ' s turn Dark Yugi used " Magic Mist " to surround the monsters in water vapor and remove the poisonous pollen , preventing the ATK of " Gaia " from further reducing . Haga ' s turn Haga attacked and destroyed " Gaia the Dragon Champion " with " Great Moth " ( Dark Yugi : 600 → 100 Life Points ) . He then began to celebrate that he had won . Dark Yugi ' s turn Dark Yugi laughed that Haga has fallen into his trap . He explained that " Gaia the Dragon Champion " had been decoy and then Summoned " Summoned Skull " . Haga was relieved , thinking he had been worried over nothing . " Great Moth " had more ATK than " Summoned Skull " and if they battled Dark Yugi would lose the rest of his Life Points . Dark Yugi pointed out the real reason , he had played " Magic Mist " ; " Great Moth " had become wet and more conductive to the electric attack of " Summoned Skull " . " Summoned Skull " ( " Summoned Skull " : 2500 → 3100 ATK ) attacked and destroyed " Great Moth " ( Haga : 450 → 0 Life Points ) , winning the Duel for Dark Yugi . Aftermath . Dark Yugi took the two Star Chips that Haga had wagered , leaving him with none . Dark Yugi noted how the champion of Japan was the first to be eliminated Since Haga no longer needed his Duel Glove , Katsuya Jonouchi , who still needed one , took it .
