Zimone, Quandrix Prodigy + Retreat to Coralhelm + Selesnya Sanctuary + Horizon Explorer

Zimone, Quandrix Prodigy

Retreat to Coralhelm

Selesnya Sanctuary

Horizon Explorer

How it works

1. Activate Zimone's first ability by paying 1 and tapping it, putting Selesnya Sanctuary from your hand onto the battlefield untapped due to Horizon Explorer.
2. When Selesnya Sanctuary enters the battlefield, it and Retreat to Coralhelm trigger.
3. Holding priority, activate Selesnya Sanctuary by tapping it, adding .
4. Resolve the Selesnya Sanctuary trigger from step 2, returning itself from the battlefield to your hand.
5. Resolve the Retreat to Coralhelm trigger, untapping Zimone.
6. Repeat.

This loop is a masterclass in turning a gentle bounce-land into a high-octane engine, powered entirely by how smoothly the permanent pieces lock together. With Horizon Explorer on the board ensuring your lands enter untapped, you can use Zimone, Quandrix Prodigy to drop Selesnya Sanctuary straight from your hand; the Sanctuary's own entry trigger bounces itself right back to your hand, while its mana ability lets you tap it for {G}{W} before it leaves. Meanwhile, Retreat to Coralhelm sits back and watches the landfall triggers roll in, using its untap mode to ready Zimone for the next iteration. You end up with a self-sustaining loop that generates infinite green and white mana alongside an endless parade of landfall triggers.
