Black Death Apostle

Creature cards in your graveyard have unearth.
The unearth cost is equal to the card's mana cost.
(Pay the card's mana cost: Return it to the battlefield.
The creature gains haste. Exile it at the beginning of
the next end step or if it would leave the battlefield.
Unearth only as a sorcery.)
{3}{b}{b}, {t}: Put target creature card from a
graveyard onto the battlefield under your control.
