Durnen, Bloodfinger Minstrel

Whenever a creature dies, put a +1+1
counter on Durnen. Then Durnen deals damage equal to the number of +1+1 counters on it to that creature's controller.
"So many minstrels sing of love and chivalry, I thought there would be a niche for songs of blood
and agony. Sadly, I fear Emberon is not yet
ready for my genius."
