Emeria Shepherd + World Shaper + Umbral Collar Zealot + Coastal Hornclaw

Emeria Shepherd

World Shaper

Umbral Collar Zealot

Coastal Hornclaw

How it works

1. Activate Coastal Hornclaw 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 ingenious loop transforms basic resource management into a perpetual engine of resurrection. By using Coastal Hornclaw to intentionally strip your board of lands, you set the stage to sacrifice World Shaper to Umbral Collar Zealot, triggering the Shaper's death ability to flood the battlefield with every land currently resting in your graveyard. Those mass entries immediately awaken Emeria Shepherd's landfall ability multiple times, allowing you to bypass your hand and yank World Shaper—plus any other nonland permanents you fancy—directly back onto the battlefield.
