If you have 3 or more "Destiny HERO" monsters in your Graveyard: You can discard this card, then target 1 "Destiny HERO" monster in your Graveyard; Special Summon it to your opponent's field in Defense Position. Negate any Spell Cards or effects you activate, and if you do, destroy that card. During your Standby Phase: You can banish this card and 1 "Destiny HERO" monster from your Graveyard; each player chooses 1 Normal Spell Card from their Deck and places it on top of their Deck.
It can target itself, but there has to be a legal target in there to activate its effect. (Which there usually will be, but you could have been a weirdo and discarded 3 Destiny HERO - Dogma as the only D-HEROes in your GY or something.)
It’s good for negating opponents spell cards but the problem here is they can also be used for their tribute summon right?
