This brilliant loop locks down the vintage format by chaining extra turns indefinitely, using Warden of the Eye as a recursive engine to continuously reclaim Time Walk from your graveyard. While the Warden already secures your infinite turns by looping the spell each time it enters the battlefield, Dour Port-Mage elevates the sequence from a simple lock into a game-winning advantage. By utilizing Dour Port-Mage's active ability to bounce the Warden back to your hand, you trigger its passive draw ability to harvest a card with every single iteration, ensuring you not only control all the turns to come, but draw your entire deck in the process.
