Athreos, Shroud-Veiled (THB 269)

Legendary Enchantment Creature — God • Mana cost: {4}{W}{B} • Theros Beyond Death • Mythic

Indestructible
As long as 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.
