By leveraging Agatha of the Vile Cauldron to slash the activation cost of Emiel the Blessed down to just a single generic mana, we unlock an engine that loops for free. Each iteration blinks Brazen Freebooter, which triggers the pirate to generate a Treasure token upon re-entering the battlefield. Sacrificing that very Treasure provides the exact mana needed to fuel Emiel the Blessed once again, letting you repeat the process indefinitely for an endless chain of entering and leaving the battlefield.
