This loop relies on Agatha of the Vile Cauldron to act as the ultimate cost-reducer, shaving {3} off Emiel the Blessed's blink ability thanks to Agatha's power. With that activation cost brought down to just a single mana, Emiel can repeatedly exile and return Patron of the Arts to the battlefield. Every time Patron of the Arts re-enters, its triggered ability generates a brand new Treasure token that you can immediately crack to fund the next blink, creating an endless engine for triggers.
