Emeria Shepherd + Aftermath Analyst + Overgrown Estate + Spelunking

Emeria Shepherd

Aftermath Analyst

Overgrown Estate

Spelunking

How it works

1. Activate any number of lands by tapping them, adding at least 3.
2. Activate Overgrown Estate by sacrificing a land.
3. Repeat step 2 until you control no lands.
4. Activate Aftermath Analyst by paying 3 and sacrificing it, returning all lands from your graveyard to the battlefield untapped due to Spelunking.
5. When the lands enter, Emeria Shepherd triggers that many times.
6. Resolve an Emeria Shepherd trigger that was triggered by a Plains, returning Aftermath Analyst from your graveyard to the battlefield.
7. Resolve all other Emeria Shepherd triggers, returning any number of nonland permanents from your graveyard to either your hand or the battlefield.
8. Repeat.

This intricate self-sustaining loop relies on converting your entire land base into fuel for Overgrown Estate, which bins your lands to pad your life total while filling your graveyard. Once your lands are gone, you cash in {3}{G} to activate Aftermath Analyst, dragging every single one of those lands straight back from the graveyard. Thanks to Spelunking ensuring those lands enter the battlefield untapped, their simultaneous arrival triggers Emeria Shepherd a multitude of times. A single Plains-triggered return brings Aftermath Analyst right back to your side, while the remaining triggers let you recur any nonland permanents you desire directly to the battlefield or your hand, setting the stage for endless repetition.
