Anpu, Patient Judge

Indestructible
As long as your devotion to black is less than 6,
Anpu isn't a creature.
Whenever a creature with unequal power and toughness
enters or leaves an opponent's graveyard,
that player loses 2 life.
Dogs and Humans you control
with unequal power and toughness X or less
balance up to the higher value,
where X is your devotion to black.
