Emeria Shepherd + World Shaper + Zuran Orb + Umbral Collar Zealot

Emeria Shepherd

World Shaper

Zuran Orb

Umbral Collar Zealot

How it works

1. Activate Zuran Orb 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 intricate loop transforms a quiet graveyard into an unstoppable engine, centered around Emeria Shepherd's ability to cheat nonland permanents directly onto the battlefield whenever a Plains enters. You begin by cycling your lands away using Zuran Orb to fuel your life total while loading the graveyard, then feed World Shaper to Umbral Collar Zealot so its death trigger can flood the board with those exact lands. As every single land drops back into play, Emeria Shepherd triggers en masse to resurrect World Shaper right back alongside any other treasures you desire.
