Deep-Eyes White Dragon (MVP1-EN005) - The Dark Side of Dimensions Movie Pack Unlimited

When a face-up "Blue-Eyes" monster(s) you control is destroyed by battle or an opponent's card effect, and you have a Dragon-Type monster in your Graveyard: You can Special Summon this card from your hand, and if you do, inflict 600 damage to your opponent for each Dragon-Type monster with different names in your Graveyard. If this card is Normal or Special Summoned: Target 1 Dragon-Type monster in your Graveyard; this card's ATK becomes equal to that monster's. If this card on the field is destroyed by a card effect: Destroy all monsters your opponent controls.
