Butcher of Sinners

Menace (This creature can't be blocked except by two
or more creatures.)
Rampage 2 (Whenever this creature becomes blocked,
it gets +2/+2 until end of turn for each creature
blocking it beyond the first.)
Whenever you destroy a black permanent, put a
+1/+1 counter on this card.
A demon that kills demons, peculiarly funny.
