How it works
Activate Overgrown Estate by sacrificing a land.
Repeat step 1 until you control no lands.
Activate Bartolomé del Presidio 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 Bartolomé del Presidio ability.
Repeat
This clever loop turns a graveyard into a fully recursive engine by cycling your entire land base back and forth between the battlefield and the graveyard using Overgrown Estate to feed the cycle. Once your lands are binned, sacrificing World Shaper to Bartolomé del Presidio triggers World Shaper's death ability to flood the board with those lands all at once. This sudden influx of land drops triggers Emeria Shepherd multiple times, allowing you to instantly deploy World Shaper right back to the battlefield while pulling every other nonland permanent out of your graveyard along the way.
