Mirrorpool + Splendid Reclamation + Zuran Orb + Amulet of Vigor

Mirrorpool

Splendid Reclamation

Zuran Orb

Amulet of Vigor

How it works

1. Cast Splendid Reclamation by paying 3.
2. Holding priority, activate any number of lands you control except Mirrorpool by tapping them, adding at least 2C.
3. Activate Zuran Orb by sacrificing a land other than Mirrorpool.
4. Repeat step 3 until Mirrorpool is the only land you control.
5. Activate Mirrorpool's second ability by paying 2C, tapping and sacrificing it, copying Splendid Reclamation.
6. Resolve the Splendid Reclamation copy, returning all land cards from your graveyard to the battlefield tapped.
7. When the lands enter, Amulet of Vigor triggers that many times, untapping the lands.
8. Repeat from step 2.

This clever recursive loop turns your graveyard into a self-sustaining engine by chaining together land recycling and mana generation. You initiate the cycle by casting Splendid Reclamation, then sacrifice your entire domain to Zuran Orb to fuel Mirrorpool's copy ability while also stocking your graveyard with fresh targets. Once Mirrorpool sacrifices itself to copy that initial spell, the resolving copy dumps every land right back onto the battlefield. Thanks to Amulet of Vigor, those lands immediately untap as they enter, leaving you with an ocean of mana and a pristine setup to cast and copy Splendid Reclamation all over again.
