Kemarus, Tethered Rage

Flying, rage (When this creature blocks or becomes blocked, it deals damage equal to the amount of
+1/+1 counters on it to target creature an opponent controls.)
Whenever another creature dies, you may put a +1/+1 counter on Kemarus, Fire Enraged.

"When the lost King returned and unleashed
Kemarus upon Tinlar once more, a new tale of terror burned it's way across the land."
