Kiora's Follower + Judge of Currents + Synth Infiltrator

Kiora's Follower

Judge of Currents

Synth Infiltrator

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

This clever loop revolves around a mutual untap dance between Kiora's Follower and Synth Infiltrator, which enters the battlefield copying Kiora's Follower so that both permanents can untap one another indefinitely. While they continuously toggle back and forth between tapped and untapped states, Judge of Currents sits quietly on your board to passively watch the action, triggering its ability every single time either Merfolk becomes tapped. The result is an endless cycle of activations that rewards your board state with infinite life and infinite lifegain triggers.
