Emeria Shepherd + Aftermath Analyst + Lithatog + Tiller Engine

Emeria Shepherd

Aftermath Analyst

Lithatog

Tiller Engine

How it works

1. Activate any number of lands by tapping them, adding at least 3.
2. Activate Lithatog 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 tapped.
5. When the lands enter, Emeria Shepherd and Tiller Engine trigger that many times.
6. Resolve all Tiller Engine triggers, untapping each land that entered.
7. Resolve an Emeria Shepherd trigger that was triggered by a Plains, returning Aftermath Analyst from your graveyard to the battlefield.
8. Resolve all other Emeria Shepherd triggers, returning any number of nonland permanents from your graveyard to either your hand or the battlefield.
9. Repeat.

This intricate loop begins by feeding your lands to Lithatog, clearing the board of your own real estate to prep the graveyard for Aftermath Analyst. Once Aftermath Analyst sacrifices itself using the mana you floated, its ability sweeps every land back onto the battlefield tapped. That sudden influx of geography wakes up Tiller Engine to instantly untap those lands, while simultaneously letting Emeria Shepherd cheat Aftermath Analyst and any other nonland permanent straight from your graveyard back to the battlefield.
