" Flying Fish " attack s and destroys Joey ' s Set monster , " Parasite Paracide " ( 500 / 300 ) . Since Joey has no monsters to Tribute , the Flip Effect of " Parasite Paracide " doesn ' t activate . ( In the real game , " Parasite Paracide " would have been shuffled into Mako ' s Deck and further effects would be activated if he were to draw it . This exchange was presumably done for comedic effect . ) Turn 3 : Joey Joey draws . He then Set s a monster . Turn 4 : Mako Mako draws . He then Set s a card . Turn 5 : Joey Joey draws " Garoozis " .
