Kiora's Follower + Judge of Currents + Mirror Image

Kiora's Follower

Judge of Currents

Mirror Image

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

This clever setup transforms a simple mutual untap loop into an endless fountain of life by exploiting how permanents interact upon becoming tapped. With Mirror Image having entered the battlefield as a copy of Kiora's Follower, the two creatures can endlessly target and untap one another, as each activation naturally satisfies the requirement of the other. Meanwhile, Judge of Currents sits quietly on the battlefield watching the taps roll in, turning every single reciprocal activation into a triggered instance of life gain.
