Empress of Horror

Descend (If you have eight or more creature cards in
your graveyard, you get the crypt's blessing for the
rest of the game.)
At the beginning of your upkeep, mill a card.
Exile a creature card from your graveyard and
pay its mana cost: Create a token that's a copy
of that card. Activate this ability only if you have
the crypt's blessing and only any time you could
cast a sorcery.
