Zimone, Quandrix Prodigy + Retreat to Coralhelm + Oboro, Palace in the Clouds + Nissa, Resurgent Animist

Zimone, Quandrix Prodigy

Retreat to Coralhelm

Oboro, Palace in the Clouds

Nissa, Resurgent Animist

How it works

1. Activate Zimone's first ability by paying 1 and tapping it, putting Oboro, Palace in the Clouds from your hand onto the battlefield.
2. When Oboro, Palace in the Clouds enters the battlefield, Retreat to Coralhelm and Nissa trigger.
3. Resolve the Nissa trigger, adding one mana of any color.
4. Resolve the Retreat to Coralhelm trigger, untapping Zimone.
5. Activate Oboro's first ability by tapping it, adding .
6. Activate Oboro's last ability by paying 1, returning it from the battlefield to your hand.
7. Repeat.

This loop creates an endless sequence of land drops by continuously bouncing and replaying Oboro, Palace in the Clouds. Zimone, Quandrix Prodigy provides the engine to drop the land from your hand, which in turn triggers Retreat to Coralhelm to untap Zimone so she can repeat the process. Meanwhile, Nissa, Resurgent Animist converts each of those entering lands into a free mana of any color, generating the exact resource needed to fund Zimone's activation and Oboro's return to your hand.
