Looming Gonoped

Swampwalk, mental annihilation (When this creature deals combat damage to a player, each player exiles that many cards from their hand.)
Looming Gonoped enters the battlefield with three -1/-1 counters on it.
Pure insanity - At the beginning of your endstep, if no player has any cards in hand, remove all -1/-1 counters from Looming Gonoped and draw two cards.
