Emrakul's Blessing

When you cast this spell, counter it unless {b} was spent to cast it.
Destroy target creature with converted mana cost
X. If that creature was a friendly creature, you
may choose a creature card with a converted mana cost of up to X plus 2 in your hand and put it onto the battlefield.
Emrakul's presence warps and twists that which you know into the unrecognizable.
