Emeria Shepherd + World Shaper + Overgrown Estate + Thermopod

Emeria Shepherd

World Shaper

Overgrown Estate

Thermopod

How it works

1. Activate Overgrown Estate by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Thermopod 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. Repeat

This loop turns your graveyard into a perpetual motion machine by leveraging Overgrown Estate to rapidly strip your board of lands, which Thermopod then allows you to follow up by sacrificing World Shaper for red mana. When World Shaper perishes, its death trigger dumps every land from your graveyard straight onto the battlefield, creating a massive wave of landfall triggers for Emeria Shepherd. Because those lands include Plains, Emeria Shepherd's ability can seamlessly pluck World Shaper right back out of the graveyard to do it all over again, while simultaneously salvaging every other nonland permanent you could ever want.
