This loop achieves infinite enters-the-battlefield and leaves-the-battlefield triggers by leveraging Training Grounds to slash Emiel the Blessed's blink ability down to a cost of just one mana. Every time Emiel the Blessed blinks Swashbuckler Extraordinaire, the pirate's entry triggers to manufacture a fresh Treasure token. By cracking that very same Treasure token for mana, you instantly generate the exact resource needed to repeat the process with Emiel the Blessed all over again—all while Swashbuckler Extraordinaire sits safely in the background, ensuring a steady supply of artifacts to fuel the engine.
