Osira the Infinite Deceit

Indestructible
As long as your devotion to green, white, blue, and black is less than sixteen, Osira the Infinite Deceit isn't a creature.
Whenever you draw a card, if Osira is a creature, put a +1/+1 counter on each creature you control, then you gain 3 life and scry 4. Then, each opponent discards two cards.
