Zameraq, The Worlds End

Trample, Unleash (You may have this creature enter the battlefield with a +1/+1 counter on it. It can't block as long as it has a +1/+1 counter on it.)
When Zameraq enters the battlefield, deal 3 damage to each other creature without flying. If a creature dealt damage this way would die, exile it instead.
Other demons creatures you control have unleash.
