Emeria Shepherd + Aftermath Analyst + Tiller Engine + Need for Speed

Emeria Shepherd

Aftermath Analyst

Tiller Engine

Need for Speed

How it works

1. Activate any number of lands by tapping them, adding at least 3.
2. Activate Need for Speed 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 clever loop begins by funneling your lands into the graveyard through Need for Speed, which happily converts them into fuel to grant your creatures haste. Once your land base rests entirely in the graveyard, you unleash Aftermath Analyst's activation to flood the battlefield with every single one of those lands tapped. This massive wave of arrivals awakens Tiller Engine, whose triggered ability instantly untaps each of those newly entered lands so they are ready to tap for mana all over again. Meanwhile, Emeria Shepherd watches the landfall celebration and leverages the influx of Plains to drag Aftermath Analyst right back out of the graveyard and onto the battlefield, setting the stage to recur any other nonland permanent you desire while feeding an endless cycle of sacrifice, death, and landfall triggers.
