Emeria Shepherd + World Shaper + Umbral Collar Zealot + Troubled Healer

Emeria Shepherd

World Shaper

Umbral Collar Zealot

Troubled Healer

How it works

1. Activate Troubled Healer 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 clever loop turns the graveyard into a revolving door by weaponizing resource depletion and rebirth. First, you clear your board by feeding your lands to Troubled Healer's activation cost, loading the graveyard while keeping the engine primed. Then, Umbral Collar Zealot sacrifices World Shaper, triggering its death ability to flood the battlefield with all those departed lands at once. That sudden influx of terrain causes Emeria Shepherd's landfall ability to trigger en masse, letting you bypass the hand and place World Shaper directly back onto the battlefield to do it all over again.
