Emeria Shepherd + World Shaper + Bloodflow Connoisseur + Trenching Steed

Emeria Shepherd

World Shaper

Bloodflow Connoisseur

Trenching Steed

How it works

1. Activate Trenching Steed 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 clever loop sets up an engine of life, death, and reclamation using your graveyard as an endless resource. You begin by paying the cost of Trenching Steed over and over to strip your board of lands, feeding them straight into the graveyard while fueling Bloodflow Connoisseur as the ultimate executioner. When you sacrifice World Shaper to the Connoisseur, its death trigger sweeps every single one of those lands right back onto the battlefield tapped. This mass influx of lands activates Emeria Shepherd's landfall ability multiple times, allowing you to instantly loop World Shaper and any other fallen permanents back into play.
