Consume 3 (When this creature enters the
battlefield, an opponent of your choice may sacrifice
any number of creatures with total power 3 or
greater. If they don't, they lose 3 life.)
When All-Consuming Chimera enters the

the battlefield with 3 +1/+1 counters on it.
Hunger unending, pain relenting.
