Toxrill, the Corrosive

Maha, Its Feathers Night

How it works

1. At the beginning of your end step, Toxrill's first ability triggers, putting a slime counter on each creature your opponents control.
2. Because your opponents' creatures are now 0/0 due to Maha and Toxrill's static effects, the creatures die as a state-based action due to having zero toughness unless there is an effect boosting their toughness.
3. Repeat during each of your end steps.
