If this card is sent to the graveyard from anywhere, you may exile it instead. If you do, you can search your library for up to one Zombie or Skeleton creature spell with converted mana cost 5 or more, reveal it, and add it to your hand. If you control an enchantment named Zombie World, you can place that creature onto the battlefield tapped instead. In either case, your library is then shuffled. You can only use this ability once per turn.
