Queen NecriZoa

Ward {2}, flying, wither

At the beginning of your end step, destroy all
creatures your opponents control with -1/-1
counters on them. Create a 1/2 black Arathim
Zoa creature token with flying and wither for
each creature destroyed this way.

A monster filled with blind hate, resentment, and
beastly rage, something born in the pit of despair
and darkness.
