Shifting Woodland + Aftermath Analyst + Overgrown Estate + Amulet of Vigor

Shifting Woodland

Aftermath Analyst

Overgrown Estate

Amulet of Vigor

How it works

1. Activate Overgrown Estate by sacrificing any land except Shifting Woodland, causing you to gain 3 life.
2. Repeat step 1 until you control no other lands except Shifting Woodland.
3. Activate Shifting Woodland's second ability by paying 2, causing it to become a copy of Aftermath Analyst until end of turn.
4. Activate Shifting Woodland by paying 3 and sacrificing it, returning it and all other land cards from your graveyard to the battlefield tapped.
5. When the lands enter the battlefield, Amulet of Vigor triggers that many times, untapping the lands.
6. Activate any number of lands by tapping them, adding at least 5.
7. Repeat.

This clever loop relies on turning your lands into recursive engines, starting with Overgrown Estate to trim away excess lands and pad your life total. By utilizing Shifting Woodland's delirium ability to morph into a copy of Aftermath Analyst, you gain access to the Analyst's powerful sacrifice effect right from the graveyard. Sacrificing your makeshift Analyst brings your entire graveyard of lands flooding back, where Amulet of Vigor immediately steps in to untap them all as they enter. This generates a massive surplus of mana and triggers, allowing you to feed Overgrown Estate once more and repeat the entire sequence indefinitely.
