Emeria Shepherd + Lumra, Bellow of the Woods + Overgrown Estate

Emeria Shepherd

Lumra, Bellow of the Woods

Overgrown Estate

How it works

1. Cast Lumra by paying 4.
2. When Lumra enters, it triggers.
3. Holding priority, activate Overgrown Estate by sacrificing a land.
4. Repeat step 3 until you control no lands.
5. When you sacrifice the last land, Lumra will die as a state-based action due to having 0 toughness.
6. Resolve the Lumra trigger from step 2, causing you to mill four cards and return all lands from your graveyard to the battlefield tapped.
7. When the lands enter, Emeria Shepherd triggers that many times.
8. Resolve an Emeria Shepherd trigger that was triggered by a Plains, returning Lumra from your graveyard to the battlefield.
9. Repeat from step 2.

This clever loop transforms a mountain of self-mill and sacrifice into an unstoppable engine of recursion. By using Overgrown Estate to feed lands into the graveyard and shrink Lumra, Bellow of the Woods down to zero toughness, you clear the way for Lumra's own entry trigger to flood the battlefield with every land you just binned. That massive wave of landfalls awakens Emeria Shepherd, whose Plains-specific trigger plucks Lumra right back out of the graveyard to restart the entire devastating cycle.
