Mirrorpool + Splendid Reclamation + Zuran Orb + Tiller Engine

Mirrorpool

Splendid Reclamation

Zuran Orb

Tiller Engine

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, Tiller Engine triggers that many times, untapping the lands.
8. Repeat from step 2.

This intricate loop transforms a massive graveyard into a self-sustaining engine by cycling your entire land base back and forth through the battlefield. As Splendid Reclamation pulls all your sacrificed lands straight back into play tapped, Tiller Engine's static trigger steps in to immediately untap them, fueling your mana pool while keeping your resources ready for the next iteration. Zuran Orb acts as the catalyst to pitch those lands into the graveyard at instant speed, while Mirrorpool provides the ultimate payoff by sacrificing itself to copy the initial Splendid Reclamation, ensuring the cycle repeats indefinitely for infinite value.
