Kiora's Follower + Judge of Currents + Vizier of Many Faces

Kiora's Follower

Judge of Currents

Vizier of Many Faces

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

This clever loop relies on Kiora's Follower and Vizier of Many Faces—which has entered as a copy of that same untapper—taking turns tapping to untap one another indefinitely. Because both creatures are Merfolk, Judge of Currents sits quietly on the battlefield watching the taps, turning every back-and-forth activation into an endless fountain of life.
