I am pretty sure that this card will allow you to use Bolner to replay a battlecry from a previous turn because Bolner isn't a battlecry effect. This effect is insane, but surviving long enough to pull off the combo will be the hard part. I think this will see play, but it probably won't be game winning (most of the time).

I would take out feed the animals and beastmaster. Really low rate or return on those.
