Aela, Prodigal Apprentice

First Strike
Whenever you cast a blue or red spell, you may
pay {2}{u}{r}. If you do, exile Aela, Prodigal Apprentice and create a 5/5 black Hellcat
creature token with double strike. When that
token leaves the battlefield, return Aela to the battlefield under your control.
