Living Plane + Doomwake Giant

Living Plane

Doomwake Giant

How it works

1. Cast Living Plane by paying 2.
2. Living Plane enters the battlefield, triggering Doomwake Giant, giving all opposing creatures -1/-1 until end of turn.
3. Because Living Plane causes all lands to be 1/1 creatures, all of your opponent' lands die as a state-based action due to having zero or less toughness.
