This loop is a masterclass in recycling your best spells, turning Kykar, Zephyr Awakener into both a blink engine and a token generator whenever you cast a noncreature spell. By pointing Kykar's triggered ability at Warden of the Eye when you cast Temporal Manipulation, you tuck the Warden safely away until the end step. When the Warden finally returns, its enters-the-battlefield ability triggers to fish Temporal Manipulation right back out of your graveyard and into your hand. Because Temporal Manipulation grants you an extra turn, you can simply recast the spell, repeat the process on each successive turn, and lock down the game with an endless procession of your own turns.
