Bloodfire Overlord

Flying, haste, mutate 3 (If this creature would untap during your untap step, you may instead put three +1/+1 counters on it.)
Whenever a creature untaps, Bloodfire Overlord deals damage equal to the number of +1/+1 counters on it to that creature's controller.
The demons of Malacol are beings birthed from the darkest nightmares. But even that didn't stop the Masters of Evolution turning their gifts upon
their own kind.
