Ashaya, Soul of the Wild + Celestial Dawn + Emeria Shepherd + Goblin Bombardment

Ashaya, Soul of the Wild

Celestial Dawn

Emeria Shepherd

Goblin Bombardment

How it works

1. Cast any creature by paying its mana cost.
2. When the creature enters as a Plains due to Ashaya and Emeria Shepherd, Emeria Shepherd triggers.
3. Holding priority, activate Goblin Bombardment by sacrificing the creature cast in step 1.
4. Resolve the Emeria Shepherd trigger, returning another creature from your graveyard to the battlefield.
5. Repeat from step 2.

This intricate loop hinges on Ashaya, Soul of the Wild turning all your nontoken creatures into Forest lands, which Celestial Dawn then turns into Plains lands while simultaneously allowing your white mana to be spent as any color. Because every creature you cast is now a Plains, its entry triggers Emeria Shepherd's landfall ability to return a card from your graveyard straight to the battlefield. By using Goblin Bombardment to sacrifice that creature in response, you can immediately loop the process to generate infinite damage, sacrifice triggers, and return every creature from your graveyard.
