Emeria Shepherd + Aftermath Analyst + Zuran Orb + Horizon Explorer

Emeria Shepherd

Aftermath Analyst

Zuran Orb

Horizon Explorer

How it works

1. Activate any number of lands by tapping them, adding at least 3.
2. Activate Zuran Orb 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 Horizon Explorer.
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 recursive loop relies on feeding your own lands into Zuran Orb to stock your graveyard, which is then dramatically paid off by Aftermath Analyst's sacrifice ability to flood the board with lands all at once. Because Horizon Explorer ensures those returning lands enter untapped, you can easily filter your mana to pay for Aftermath Analyst and repeat the process indefinitely. Each wave of land drops triggers Emeria Shepherd over and over, allowing you to not only pull Aftermath Analyst straight back from the graveyard onto the battlefield when a Plains enters, but also recycle every other nonland permanent you desire.
