Emeria Shepherd + World Shaper + Goblin Bombardment + Coastal Hornclaw

Emeria Shepherd

World Shaper

Goblin Bombardment

Coastal Hornclaw

How it works

1. Activate Coastal Hornclaw by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Goblin Bombardment by sacrificing World Shaper.
4. When World Shaper dies, it triggers, return all lands from your graveyard to the battlefield tapped.
5. When the lands enter, Emeria Shepherd triggers that many times.
6. Resolve an Emeria Shepherd trigger that was triggered by a Plains, returning World Shaper from your graveyard to the battlefield.
7. Resolve all remaining Emeria Shepherd triggers.
8. Resolve the Goblin Bombardment ability.
9. Repeat

This loop operates as an ingenious self-sustaining cycle of sacrifice and resurrection, fueled by the recursive engine of Emeria Shepherd and World Shaper. By utilizing Coastal Hornclaw to strip away your own lands, you pave the way for World Shaper to be sent to the graveyard via Goblin Bombardment; upon its death, its triggered ability floods the battlefield with all those departed lands at once. Each land drop triggers Emeria Shepherd—with at least one of them being a Plains—which lets you bypass the hand and immediately return World Shaper straight to the battlefield, ready to be sacrificed to Goblin Bombardment all over again to deal infinite damage and perpetuate the loop.
