This clever loop turns a simple blink spell into an endless engine for your spells and artifacts. By casting Essence Flux to exile Izzet Chronarch, you trigger Storm-Kiln Artist's magecraft ability to mint a fresh Treasure token. When Izzet Chronarch returns to the battlefield, its enter-the-battlefield ability dutifully fishes Essence Flux right back out of your graveyard to hand. Sacrificing the Treasure provides the exact blue mana needed to recast the spell, sustaining the cycle indefinitely while generating an arbitrary number of artifact and creature triggers.
