Indestructible (Effects that say "destroy" don't destroy that permanent. An indestructible creature can't be destroyed by damage.)
As long as your devotion to black (Each in the mana costs of permanents you control counts towards your devotion to black.) is less than five, Erebos isn't a creature.
Whenever another creature you control dies, you may pay 2 life. If you do, draw a card.
, Sacrifice another creature: Target creature gets -2/-1 until end of turn.
