Serpent of Eternity

Trample, hexproof
Eternalize {4}{g}{g}{g} ({4}{g}{g}{g}, Exile this card
from your graveyard: Create a token that's a copy of
it, except it's a 5/5 black Zombie Serpent with no
mana cost. Eternalize only as a sorcery.)
Coiled in the river of time, it rises from the depths to
defy oblivion.
