Kiora's Follower + Judge of Currents + Chameleon, Master of Disguise

Kiora's Follower

Judge of Currents

Chameleon, Master of Disguise

How it works

1. Activate Kiora's Follower by tapping it.
2. When Kiora's Follower becomes tapped, Judge of Currents triggers, causing you to gain 1 life.
3. Resolve Kiora's Follower's ability from step 1, untapping Chameleon.
4. Activate Chameleon by tapping it.
5. When Chameleon becomes tapped, Judge of Currents triggers, causing you to gain 1 life.
6. Resolve Chameleon's ability from step 4, untapping Kiora's Follower.
7. Repeat.

This clever loop transforms a pair of mutual untappers into an endless source of life by leaning on the quiet, passive presence of Judge of Currents. As Kiora's Follower taps to untap Chameleon, Master of Disguise—which is functioning as an extra copy of the Follower—and the Chameleon returns the favor to untap the first, Judge of Currents triggers on every single tap. Because Chameleon, Master of Disguise adopts the exact characteristics of Kiora's Follower upon entering, the two creatures create a perpetual motion machine that generates infinite lifegain triggers.
