The Legend of Kuruk // Avatar Kuruk + Conjurer's Closet + Spark Double

The Legend of Kuruk // Avatar Kuruk

Conjurer's Closet

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. At the beginning of your end step, Conjurer's Closet triggers, blinking Spark Double. Choose to have it enter the battlefield as a copy of Avatar Kuruk.
3. Repeat each turn.

This loop centers on Avatar Kuruk—the transformed back side of The Legend of Kuruk—whose powerful Exhaust ability allows you to spend twenty mana to take an extra turn. Because Spark Double enters the battlefield as a nonlegendary copy of Avatar Kuruk, it retains that activated ability while bypassing the legend rule, and Conjurer's Closet neatly resets the copy every single end step by blinking it to wipe away its exhaustion and let you pay the Waterbend cost again.
