Torak, Pain Incarnate

Trample, Protection from green
Torak enters the battlefield with 5 head counters
on it.
When the toughness of a Torak goes down to 0
or if he is destroyed, remove a head counter from
him, he does not go into your graveyard.
When Torak kills another creature during your
attack step, place a head counter on a Torak.
Torak gets +1/+1 for each head counter on him.
The many faces of pain, hated by all.
