Catacomb Haunt

Look at the top three cards of a library. Exile one
of them and put the other into it's owners
graveyard. Then choose one:
•Return target creature card with cmc X or less
from your graveyard to the battlefield, where X is
the number of creature cards in all graveyards.
•Target creature gains +X/-X and lifelink,
where X is the number of cards in exile.
