This cunning loop locks down the game by stitching together endless extra turns with relentless card draw. By casting Walk the Aeons, you secure your extra turns, while Izzet Chronarch constantly digs the spell right back out of your graveyard the moment it enters the battlefield. Dour Port-Mage acts as the engine's mechanical pivot, using its activated ability to bounce Izzet Chronarch back to your hand so you can replay it, all while its passive triggered ability rewards your constant shuffling of creatures by drawing you a card every single time Izzet Chronarch leaves the battlefield.
