The Legend of Kuruk // Avatar Kuruk + Sakashima the Impostor + Y'shtola Rhul

The Legend of Kuruk // Avatar Kuruk

Sakashima the Impostor

Y'shtola Rhul

How it works

1. Activate Sakashima the Impostor 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, Y'shtola Rhul triggers, blinking Sakashima the Impostor. Choose to have it enter the battlefield as a copy of Avatar Kuruk.
3. Repeat each turn.

By copying Avatar Kuruk—the transformed backside of The Legend of Kuruk—Sakashima the Impostor gains access to a massive Exhaust waterbend ability that commands twenty mana to grant an extra turn. This steep cost is easily paid by tapping down your artifacts and creatures as helpers, and because Sakashima is a fresh permanent when blinked, its once-per-game restriction resets completely. Meanwhile, Y'shtola Rhul ties the whole engine together at your end step by exiling and returning Sakashima to the battlefield, allowing it to reset its copy identity and continuously chain into infinite turns.
