Gem of Darkness

Creatures you control have lifelink and
deathtouch.
Creature cards in your graveyard have Eternalize {x}, where X is their converted mana cost.
({x}, Exile this card from your graveyard: Create a
token that's a copy of it, except it's a 4/4 black
Zombie. Eternalize only as a sorcery.)
Any opponent may reduce their life total to
1 to destroy Gem of Darkness. This ability is
not affected by hexproof.
