Actually, this can easily lead into an infinite damage combo:
Feats: Power Attack, Cleave, Great Cleave
He has a spell component pouch to produce an arbitrary number of chickens in one round. So he walks up to an opponent, and starts pulling to get a chicken. It doesn't provoke an AoO, because it is a free action. Okay, he gets a chicken, now he kills it. He gets a free shot on his opponent thanks to Sweeping Strike from War Mind.
But wait, he killed the chicken, so he gets a Cleave. So he uses free actions to produce another chicken, and kills that with his Cleave attack. And gets a free shot on his opponent thanks to Sweeping Strike.
Infinite damage loop by level 12. Not the most optimized, but certainly the most interesting.
