Zimone, Quandrix Prodigy

Retreat to Coralhelm

Simic Growth Chamber

Horizon Explorer

How it works

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

This ingenious loop turns a simple bounce land into an engine of boundless mana. By using Zimone, Quandrix Prodigy to continually drop Simic Growth Chamber, you trigger a landfall event that Retreat to Coralhelm harnesses to untap Zimone again. Meanwhile, Horizon Explorer ensures your lands enter the battlefield ready to use, letting you tap the returning Simic Growth Chamber for mana in response to its own bounce trigger.
