Toxrill, the Corrosive, and Godhead of Awe

Prerequisites

• Toxrill, the Corrosive on the battlefield
• Godhead of Awe on the battlefield

Steps

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 Godhead of Awe and Toxrill's static effects, the creatures die as a state-based action due to having zero toughness
3. Repeat during each of your end steps

Results

• Reduce each opposing creature's toughness to zero during each of your end steps
