Exstinctio Natorum

Indestructible, hexproof

As long as your devotion to black is less than eight, Exstinctio Natorum isn't a creature.

Whenever you sacrifice a creature, each opponent loses 1 life and you gain 1 life, than if it weren't a token, create a 1/1 black Horror token with: "This creature mana value is {b}{b}."

Just waiting to become, here it comes, here it comes.
Gathering our tongues, here it comes, here it comes.
