Emeria Shepherd + World Shaper + Thermopod + Trenching Steed

Emeria Shepherd

World Shaper

Thermopod

Trenching Steed

How it works

1. Activate Trenching Steed 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 self-sustaining loop turns a graveyard full of resources into an overwhelming cascade of value by feeding World Shaper to Thermopod, which immediately triggers its death ability to flood the battlefield with lands. Those entering lands trigger Emeria Shepherd, allowing you to bypass the hand and place World Shaper straight back onto the battlefield whenever a Plains arrives. Meanwhile, Trenching Steed acts as the crucial outlet to strip your board of lands in the first place, ensuring you can repeat the cycle endlessly to generate infinite red mana and reap every landfall and sacrifice trigger your heart desires.
