The full decklist for an unreleased Magic: The Gathering Secret Lair Commander deck called "Odds and Ends" has leaked online, revealing an unusually valuable set of reprints. The deck, built around the commander Yennett, Cryptic Sovereign, was apparently sent to someone by mistake ahead of its official release, and has since been shared on Reddit and deck-building sites including Moxfield and Archidekt. The leak matters to collectors and players because it exposes both the strategic design of a forthcoming officially licensed product and its significant resale value before Wizards of the Coast has made it available.

Yennett's ability lets players cast odd-cost cards for free from the top of their library, so the 100-card deck is stacked with powerful, expensive odd-mana-value cards such as Void Winnower, Approach of the Second Sun and Profane Transfusion, alongside library-manipulation staples like Brainstorm and Ponder. Existing individual copies of the cards in the deck are estimated to be worth a combined $300–$448, with the standout being Esper Sentinel, a sought-after one-mana Commander staple currently reselling for around $60 due to scarcity.
