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 white and black (Each or in the mana costs of permanents you control counts towards your devotion to white and black.) is less than seven, Athreos isn't a creature. At the beginning of your end step, put a coin counter on another target creature. Whenever a creature with a coin counter on it dies or is put into exile, return that card to the battlefield under your control.
