Oryx, The Taken King

Flying, Vigilance, Menace

{x}: Exile target creature an opponent controls with mana value X or less. Create a token copy of it, but it is black and white, looses all typings and becomes a wraith.

Wraiths you control gain +1/+1.

Sword Logic—Creatures can only be blocked by one creature at any given time. When a creature destroys another creature by combat damage, put a +1/+1 counter on that creature.
