Emeria Shepherd + World Shaper + Overgrown Estate + Goblin Bombardment

Emeria Shepherd

World Shaper

Overgrown Estate

Goblin Bombardment

How it works

1. Activate Overgrown Estate 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 intricate sacrifice loop turns your graveyard into a perpetual engine by exploiting the relationship between mass land recursion and landfall. You begin by cycling through your lands using Overgrown Estate to convert them into life, filling your graveyard until World Shaper can be sacrificed to Goblin Bombardment. The moment World Shaper dies, its triggered ability snaps every single land back onto the battlefield tapped. This sudden influx of land drops triggers Emeria Shepherd repeatedly, allowing you to bypass the hand restriction and drop World Shaper straight back onto the battlefield as long as a Plains is among the returned lands, while your other landfall triggers fish out any remaining nonland permanents you might need.
