Primordial Creation

Flying, Lifelink
While this creature is on the battlefield under your control, your life total cannot be reduced, other permanents you control cannot be destroyed or exiled, you cannot lose the game, and you may cast cards from your graveyard.
Whenever you would gain life, gain twice that much life instead.

"My mother was creation itself. The only other being as old as my father. Her love is what guided all realities toward prosperity."—Thanatos
