How it works
Activate Troubled Healer by sacrificing a land.
Repeat step 1 until you control no lands.
Activate Yahenni 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 Yahenni ability.
Repeat
This intricate self-sustaining loop relies on a clever cycle of sacrifice, death, and resurrection to dominate the battlefield. You begin by using Troubled Healer to clear your own lands away, feeding them into the graveyard so that Yahenni, Undying Partisan can safely sacrifice World Shaper. The moment World Shaper hits the dirt, its death trigger fires to return all those fallen lands straight to the battlefield tapped, which in turn floods the stack with Emeria Shepherd's powerful landfall triggers. Because those lands include Plains, the Shepherd can instantly pluck World Shaper right back out of the graveyard and onto the battlefield to do it all over again, generating infinite sacrifice, death, and landfall triggers.
