Chaos Berserker

Level Up 1/2 (Whenever this creature attacks or
blocks, it randomly gains +1/+0 or +0/+1 after the
combat if it is still in play. The maximum power and toughness it can gain through this method is +1/+2)
Barbarians make great soldiers because they have
simple needs: warm food, enough ale to addle their
brains, and a dry place to sleep. - Balathustrius
