Kiora's Follower + Judge of Currents + Undercover Operative

Kiora's Follower

Judge of Currents

Undercover Operative

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

This delightful little loop relies on mutual tapping and untapping between Kiora's Follower and Undercover Operative—which copies Kiora's Follower upon entering the battlefield—to create an endless reciprocating engine. As each of these two identical creatures taps to untap the other, Judge of Currents sits quietly on your board watching the Merfolk go to work, triggering its ability every single time either creature becomes tapped. Because Undercover Operative safely copies the untap ability while bringing along a protective shield counter for safety, the pair can bounce the active state back and forth indefinitely to farm as much life as you could ever want.
