Anubri the Infinite Yearning

Indestructible
As long as your devotion to blue, black, red, and green is less than sixteen, Anubri the Infinite Yearning isn't a creature.
Whenever an opponent draws a card, casts a spell, or attacks with a creature, if Anubri is a creature, that player loses 10 life unless he or she sacrifices two nonland permanents.
