Whoops, I forgot to include Roze's effect. Someone really needs to make some /cuckquean/ art work of Roze and Raye.
If a "Sky Striker Ace" monster(s) other than "Sky Striker Ace - Roze" is Normal or Special Summoned: You can Special Summon this card from your hand. While this card is in your GY, if an opponent's monster(s) in the Extra Monster Zone is destroyed by battle, or leaves the field because of your card effect: You can Special Summon this card, then you can negate the effects of 1 face-up monster your opponent controls until the end of this turn. You can only use each effect of "Sky Striker Ace - Roze" once per turn.
