Cur Horde, Vicious Barbarian

Haste, Trample
Whenever a creature would die this turn, exile it instead.
On your post-combat step, add X +1/+1 counters on Cur Horde, Vicious Barbarian where X is how many creatures where exiled this turn.
He may be a beastly and wild man, but his loyalty towards the Misfits is unwavering.
