Emeria Shepherd + World Shaper + Thaumatog + Umbral Collar Zealot

Emeria Shepherd

World Shaper

Thaumatog

Umbral Collar Zealot

How it works

1. Activate Thaumatog by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Umbral Collar Zealot 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 Umbral Collar Zealot ability.
9. Repeat

This loop transforms your graveyard into a perpetual engine by turning Thaumatog and Umbral Collar Zealot into dedicated sacrifice outlets for your lands and creatures. You feed World Shaper to the Zealot—or simply let the Thaumatog consume your terrain—to send World Shaper into the graveyard, triggering its death ability to flood the board with your lands. Because those lands enter the battlefield, Emeria Shepherd's landfall ability triggers en masse, pulling World Shaper straight back to the battlefield while dredging up any other nonland permanents you might need.
