The Legend of Kuruk // Avatar Kuruk + Teleportation Circle + Spark Double

The Legend of Kuruk // Avatar Kuruk

Teleportation Circle

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, Teleportation Circle triggers, blinking Spark Double. Choose to have it enter the battlefield as a copy of Avatar Kuruk.
3. Repeat each turn.

By leveraging Teleportation Circle to continuously blink Spark Double at the beginning of your end step, you can reset its identity so it re-enters the battlefield afresh as a nonlegendary copy of Avatar Kuruk (the transformed back face of The Legend of Kuruk // Avatar Kuruk). This clever maneuver bypasses the once-per-game restriction of the card's powerful exhaust ability. By repeatedly paying the Waterbend cost on each extra turn you generate, you chain infinite turns and lock down the game.
