This elegant loop turns Emiel the Blessed into a self-sustaining engine by dramatically slashing activation costs with Biomancer's Familiar, reducing Emiel's blink ability down to just a single mana. Every single time Plundering Pirate enters the battlefield, its triggered ability generates a Treasure token that you can immediately sacrifice for mana to fuel the next iteration of Emiel the Blessed's exile effect. Because Biomancer's Familiar ensures the activation cost is kept to the absolute minimum of one mana, the Treasure generated by Plundering Pirate pays for the exact cost required to repeat the process indefinitely, producing an infinite storm of enters-the-battlefield and leaves-the-battlefield triggers.
