Brakakos, Endbringer

Indestructible
As long as your devotion to black is less then 7 Brakakos, isn't a creature.
When Brakakos, Endbringer enters the
battlefield your life total becomes equal to the
greatest life total among players.
At the beginning of each players upkeep, if that
player has 5 or less life, that player loses the
game.
