By leveraging Avatar Kuruk's unique exhaust ability, you can invest into a massive Waterbend cost to take an extra turn, tapping down your available artifacts and creatures to help pay the way. The magic truly ignites when you pair Deadeye Navigator with a clone: by using Sakashima of a Thousand Faces to copy Avatar Kuruk, you bypass the legend rule and gain access to those same potent abilities. You can then spend a small amount of mana to blink Sakashima with Deadeye Navigator's activated ability, causing it to re-enter as a fresh copy of The Legend of Kuruk // Avatar Kuruk—resetting its once-per-game exhaustion constraint and letting you chain infinite turns back-to-back.
