How it works

—

Activate Spark Double using Avatar Kuruk's ability by paying minus for each creature and/or artifact you can tap while activating it, causing you to take an extra turn after this one.
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.
Repeat each turn.
