Zoth, Face of Destruction

Flying, Haste, Trample
Whenever a permanent is put into a graveyard
from the battlefield, put a +1/+1 counter on
Zoth, Face of Destruction.
At the beginning of each end step, remove all
counters from Zoth, Face of Destruction, and it
deals damage to any target equal to the number
of counters removed this way.
