By leveraging Panoptic Mirror’s imprint ability to tuck Capture of Jingzhou into exile, you set up an inevitable engine that triggers every single upkeep. Because Capture of Jingzhou grants you an extra turn, you will continuously loop back to a fresh upkeep step where Panoptic Mirror triggers again to cast another copy for free. This creates an unbroken sequence of infinite turns, locking your opponents out of the game entirely as you march forward through endless ages of your own making.
