Retreat to Coralhelm + Scaled Herbalist + Azorius Chancery

Retreat to Coralhelm

Scaled Herbalist

Azorius Chancery

How it works

1. Activate Scaled Herbalist by tapping it, putting Azorius Chancery from your hand onto the battlefield.
2. When Azorius Chancery enters the battlefield, it and Retreat to Coralhelm trigger.
3. Resolve the Azorius Chancery trigger, returning itself from the battlefield to your hand.
4. Resolve the Retreat to Coralhelm trigger, untapping Scaled Herbalist.
5. Repeat.

This elegant loop transforms a humble druid and a bounceland into an infinite engine. By leveraging Scaled Herbalist to repeatedly drop Azorius Chancery, you trigger the land's own drawback to return it safely back to your hand for the next iteration. Meanwhile, Retreat to Coralhelm quietly watches the chaos unfold, its landfall ability untapping the Herbalist with every single land drop to keep the entire cycle spinning effortlessly.
