The new $200 Magic: The Gathering advent calendar, the Secret Lair Countdown Kit, is released today, featuring 26 mystery cards with unique Secret Lair treatments. Only six cards have been revealed so far, including high-value cards like Phyrexian Altar valued at $65, Urza's Saga at $40, and City of Brass at $20, totaling approximately $140 in revealed value. The full list of cards remains undisclosed, and the release is expected to sell out quickly, similar to previous years. Additionally, Wizards of the Coast teases a mysterious reprint called the 'Land of 1000 Lands,' which is not an actual card but likely a reprint of the classic City of Brass, based on artwork and flavor text. This reprint could significantly increase the value of the set, as City of Brass is a staple in Commander decks and currently valued at around $15, with potential reprint value rising by $20–$30. The 'Land of 1000 Lands' might also refer to copying lands, such as Vesuva or Thespian’s Stage, with Vesuva being a more plausible candidate due to its lower current value but strategic importance in casual and Commander play. The full Secret Lair Countdown Kit will be available later today at 9 AM PT, with expectations of high demand and limited availability. Wizards has not yet confirmed the exact sale time or purchase limits, but previous releases sold out rapidly.
