Emeria Shepherd + World Shaper + Viscera Seer + Trenching Steed

Emeria Shepherd

World Shaper

Viscera Seer

Trenching Steed

How it works

1. Activate Trenching Steed by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Viscera Seer 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 Viscera Seer ability.
9. Repeat

This self-sustaining loop relies on a clever cycle of sacrifice and resurrection to tap into an engine of overwhelming value. By using Trenching Steed to strip away your own lands, you feed World Shaper to Viscera Seer, triggering World Shaper's death ability to flood the battlefield with all those sacrificed land cards at once. Each land entering the battlefield triggers Emeria Shepherd multiple times; because those lands include Plains, you can bypass your hand and return World Shaper directly to the battlefield to restart the cycle. The result is an infinite parade of sacrifices and landfall triggers that lets you recur every single nonland permanent from your graveyard while sculpting your library with Viscera Seer's scry ability.
