When this card is activated: Special Summon 1 DARK Zombie monster from your Deck or GY. When that monster leaves the field, destroy this card. That monster is unaffected by the activated effects of other non-DARK monsters. If this face-up card leaves the field: Destroy as many cards you control as possible, and if you do, take 400 damage for each card destroyed. You can only activate 1 "Castle of Vampire" per turn.
