Apocrypha, Bound and Chained

Indestructible

Whenever Apocrypha, Bound and Chained blocks or becomes blocked, create a 1/1 black Cultist creature token.

Whenever Apocrypha deals combat damage to a player, you may sacrifice up to five Cultists. If you do, Apocrypha deals X damage to any target, where X is twice the number of Cultists sacrificed this way.
