This fascinating loop turns Avatar Kuruk's backside into a repeatable engine for endless time, anchored by The Legend of Kuruk's saga chapters leading up to the transformation. By having Sakashima the Impostor enter as a copy of Avatar Kuruk, it gains the powerful Waterbend exhaust ability to buy an extra turn, which is heavily discounted by tapping your available artifacts and creatures. Then, at the beginning of your end step, Conjurer's Closet steps in to blink Sakashima the Impostor, allowing it to re-enter fresh as another copy of Avatar Kuruk and reset the once-per-game restriction of the exhaust ability. Repeating this cycle every single turn locks down the game completely with an infinite sequence of extra turns.
