Target face-up cards your opponent controls, up to the number of "Dark Fusion" and Spells that mention it in your GY; negate their effects until the end of this turn. If this card is in your GY, except the turn it was sent there: You can banish it, then target up to 5 "HERO" monsters in your GY and/or banishment; shuffle them into the Deck. You can only use each effect of "Dark Supremacy" once per turn.
