Corpse Connoisseur

When Corpse Connoisseur enters the
battlefield, you may search your library for
a creature card, put that card into your
graveyard, then shuffle.
Unearth {3}{b} ({3}{b}: Return this card from
your graveyard to the battlefield. It gains haste.
Exile it at the beginning of the next end step or
if it would leave the battlefield. Unearth only
as a sorcery.)
