Emeria Shepherd + World Shaper + Bloodflow Connoisseur + Coastal Hornclaw

Emeria Shepherd

World Shaper

Bloodflow Connoisseur

Coastal Hornclaw

How it works

1. Activate Coastal Hornclaw by sacrificing a land.
2. Repeat step 1 until you control no lands.
3. Activate Bloodflow Connoisseur 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 Bloodflow Connoisseur ability.
9. Repeat

This intricate loop turns the graveyard into a bustling workshop by transforming land management into perpetual motion. By feeding lands to Coastal Hornclaw until your board is barren, you set the stage to sacrifice World Shaper to Bloodflow Connoisseur, whose hunger grows with every iteration. That sacrifice triggers World Shaper's death ability to dump those same lands straight back onto the battlefield tapped. This sudden influx mass-triggers Emeria Shepherd, whose landfall ability allows you to pluck World Shaper right back out of the graveyard and return it directly to play.
