Mardock, God of Darkness

Indestructible
As long as your devotion to black is less than 5, Mardock isn't a creature.
Demons and Leviathans you control have Fear.
Whenever Mardock deals combat damage to
a player, or planeswalker, Destroy X number of
target nonland permanents they control, and lose
X life, where X is equal to your devotion to black.
