How it works
Activate Coastal Hornclaw by sacrificing a land.
Repeat step 1 until you control no lands.
Activate Shilgengar 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 Shilgengar ability.
Repeat
This recursive loop transforms the simple act of land-cycling into a magnificent engine of resurrection. By using Coastal Hornclaw to repeatedly sacrifice your lands into the graveyard, you fuel the sacrifice outlet Shilgengar, Sire of Famine, which in turn triggers World Shaper's death ability to flood the battlefield with those same lands tapped. Every single land that returns then awakens Emeria Shepherd's landfall ability, pulling World Shaper right back from the graveyard while allowing you to reclaim any other nonland permanent you desire. Finally, the Blood tokens generated by Shilgengar, Sire of Famine feed its own mass-reanimation ability to bring back your entire army, creating an unstoppable cycle of infinite resources and endless triggers.
