Azathoth, Nuclear Chaos

Indestructible, trample
As long as an opponent has 4 or more
cards in his or her hand, Azathoth isn't
a creature.
Azathoth, Nuclear Chaos's power and
toughness are equal to X plus the number
of creature cards in all graveyards.
When Azathoth is removed from the
battlefield, exile every other nonland
permanent from the battlefield.
