The Legend of Kuruk // Avatar Kuruk + Brago, King Eternal + Spark Double

The Legend of Kuruk // Avatar Kuruk

Brago, King Eternal

Spark Double

How it works

1. Activate Spark Double using Avatar Kuruk's ability by paying 20 minus 1 for each creature and/or artifact you can tap while activating it, causing you to take an extra turn after this one.
2. Deal combat damage to an opponent using Brago. Brago triggers, blinking Spark Double. Choose to have it enter the battlefield as a copy of Avatar Kuruk.
3. Repeat each turn.

This ingenious loop relies on turning Spark Double into a nonlegendary copy of Avatar Kuruk (the transformed back face of The Legend of Kuruk // Avatar Kuruk), allowing you to bypass the once-per-game restriction on its Exhaust waterbend ability. With Brago, King Eternal safely connecting in combat, his blink trigger resets the copied Avatar Kuruk by exiling it and returning it directly to the battlefield as a fresh Saga ready to trigger again. Because Brago’s ability lets you blink any number of your nonland permanents, the entire engine smoothly repeats every single turn to secure infinite extra turns.
