Illidan, The Anti-Mage

This spell can't be countered.
Whenever an opponent cast a noncreature spell
put a +1/+1 counter on Illidan, and it gains
Ward{1} until end of turn.
Blink - once per turn after blockers are declared
you may pay{2} and remove Illidan from combat
(this doesn't untap it), or you may put Illidan, in
combat blocked by a creature your opponent
controls.
