Yavimaya, Cradle of Growth + Life and Limb + Aether Flash

Yavimaya, Cradle of Growth

Life and Limb

Aether Flash

How it works

1. Whenever a land enters the battlefield, it enters as a 1/1 Forest Saproling due to Yavimaya and Life and Limb.
2. Aether Flash triggers, dealing 2 damage to the land.
3. The land dies as a state-based action due to having less than zero toughness.

This fascinating loop turns every land drop into instant self-destruction by reshaping the board's very foundations. With Yavimaya, Cradle of Growth making every land a Forest, Life and Limb immediately steps in to bestow both Forest and Saproling types upon them, turning every land into a 1/1 creature the moment it enters the battlefield. That sudden creature status is precisely what triggers Aether Flash, dealing 2 damage to the newly arrived land-creature and sending it straight to the graveyard before it can even tap for mana.
