Out of the Tombs - Warhammer 40,000 Commander - 46

Enchantment

Mana Cost: {2}{B}

At the beginning of your upkeep, put two eon counters on this enchantment, then mill cards equal to the number of eon counters on it.
If you would draw a card while your library has no cards in it, instead return a creature card from your graveyard to the battlefield. If you can't, you lose the game.
