Colette, Vampire Matriarch

As long as your devotion to white and black is
less than eight, Colette isn't a creature.
At your upkeep, create two 0/1 black Cleric
creature tokens.
When Colette attacks, you may sacrifice five
creature tokens. If you do, all opponents lose
15 life and you gain 15 life.
