Uristixiat, Ancient One

Flying, trample, protection from everything
Uristixiat enters the battlefield tapped with five slumber counters.
As long as Uristixiat has a slumber counter on it,
it's a land.
{t}: Add 2 mana of any color, remove a slumber counter from this Uristixiat.
When Uristixiat becomes a creature, destroy all
other creatures and draw three cards.
