How it works
Activate Overgrown Estate by sacrificing a land.
Repeat step 1 until you control no lands.
Activate Phantom Train by sacrificing World Shaper.
When World Shaper dies, it triggers, return all lands from your graveyard to the battlefield tapped.
When the lands enter, Emeria Shepherd triggers that many times.
Resolve an Emeria Shepherd trigger that was triggered by a Plains, returning World Shaper from your graveyard to the battlefield.
Resolve all remaining Emeria Shepherd triggers.
Resolve the Phantom Train ability.
Repeat
This clever self-sustaining loop relies on a clever cycle of sacrifice and resurrection, anchored by Emeria Shepherd to cheat cards directly back into play when your lands return as Plains. You begin by grinding away your own resources using Overgrown Estate to send your lands to the graveyard for a steady stream of life. Once your lands are gone, you feed World Shaper to Phantom Train; World Shaper's death trigger immediately sweeps every single land card back onto the battlefield tapped. This massive wave of land arrivals triggers Emeria Shepherd over and over, allowing you to pull World Shaper right back out of the graveyard and repeat the entire sequence indefinitely for boundless benefits.
