This clever loop comes together by using Agatha of the Vile Cauldron to slash the activation cost of Emiel the Blessed down to just a single generic mana. With that discount in place, you can continually pay to blink Galazeth Prismari, triggering its entry ability to generate a fresh Treasure token each time. Because Galazeth Prismari also grants all your artifacts the ability to tap for colored mana restricted to instants and sorceries, any incidental artifacts you control can help kickstart the engine, while the endless stream of blinking Galazeth Prismaris effortlessly fuels Emiel the Blessed's ability over and over again.
