Darth Revan

Destiny (you may cast either side of this card)
Whenever you cast a spell with Darkside, put a
+1/+1 counter on Darth Revan. Darkside
spells can't be countered if Darth Revan
is on the battlefield.
Whenever Darth Revan attacks, creatures
you control gain +X/+X, where X is Revan's
power.
