Singed, Mad Scientist

Wither (This deals damage to creatures in the
form of -1/-1 counters.)
At the beginning of your upkeep, put a -1/-1 on
target creature. Whenever a creature with a -1/-1 counter on it dies, draw a card.
At the beginning of each end step, Proliferate.
(Choose any number of permanents and/or players,
then give each another counter of each kind already
there.)
