Kiora's Follower + Judge of Currents + Auton Soldier

Kiora's Follower

Judge of Currents

Auton Soldier

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

This clever loop relies on a mutual untap cycle between Kiora's Follower and Auton Soldier, where each creature's tap ability is used exclusively to untap the other endlessly. Because Auton Soldier enters the battlefield copying a creature and isn't legendary while also being an artifact, it acts as a functional twin to Kiora's Follower that you can freely tap for profit. Meanwhile, Judge of Currents sits quietly on the battlefield watching the action, triggering to net you a point of life every single time either of your untap machines becomes tapped.
