Zivinquis, Scourge of the Weak

Whenever a creature enters the battlefield, put a
-1/-1 counter on target creature.
{2}{c}{c}: Destroy target creature with three or
more -1/-1 counters on it.
{6}{c}{c}: All creatures target opponent controls
get -3/-3 until end of turn.
When Zivinquis, Scourge of the Weak, leaves the battlefield for the first time, return it to the battlefield with two -1/-1 counters on it.
Youre all overrated... weak and undeserving
of my sympathy...
