Each Vampire creature card you own that isn't on the battlefield has madness. The madness cost is equal to its mana cost. (If you discard a card with madness, discard it into exile. When you do, cast it for its madness cost or put it into your graveyard.)

Flying When this creature enters, destroy target creature an opponent controls. Whenever a creature an opponent controls dies, exile it and put a +1/+1 counter on each Vampire you control.
