This loop is a masterclass in turning a humble blink spell into a self-sustaining engine. You cast Essence Flux targeting Shipwreck Dowser, which triggers Shipwreck Dowser's enter-the-battlefield ability to immediately fish that very same Essence Flux right back out of your graveyard. Meanwhile, Storm-Kiln Artist watches your spellcasting through its magecraft ability, minting a fresh Treasure token every step of the way to pay for the next iteration. Crack that Treasure for the blue mana you need, and you have an endless cycle of creature blinks and artifact generation that will overwhelm your opponents.
