Great Cthulhu

Trample, ward-sacrifice a non-token permanant

When Great Cthulhu enters the battlefield, creatures your opponents control get -3/-3 until end of turn.
At the beginging of your end step, draw 3 cards then discard 2 cards at random.
Whenever you discard a card, create a 1/1 black cultist creature token with
"whenever a player sacrifices a permanant, put a +1/+1 counter on this creature."
