Uthemar Witchknight

Whenever a creature an opponent controls dies,
put a +1/+1 counter on Uthemar Witchknight.
At the beginning of your upkeep, if Uthemar
Witchknight has one or more +1/+1 counters
on him, create a 0/0 black Witchknight creature
token. It enters the battlefield with a number of
+1/+1 counters on it equal to the number of
counters on Uthemar Witchknight.
