The Secret Base card, numbered 165b, is a Common land from the 2017 Magic: The Gathering Unstable set. Designed by Matt Gaser, this foil edition features a unique mechanical twist that differentiates it from standard mana-producing lands. The card allows players to add either colorless mana or one mana of any color, with the latter restricted to casting spells sharing its specific watermark. This design element adds a layer of strategic depth, rewarding deck builders who understand the watermark system. As part of the Unstable set, Secret Base embraces the unconventional and humorous tone characteristic of Magic's silver-bordered releases. The flavor text hints at the secretive nature of S.N.E.A.K., adding narrative context to the gameplay. Collectors often seek out foil versions of Unstable cards for their visual appeal and the set's nostalgic value within the Magic community. For Magic: The Gathering enthusiasts, adding Secret Base to a collection offers more than just a functional land; it represents a piece of the game's history and creativity. The foil finish enhances its collectibility, making it a standout addition for those who appreciate both the aesthetic and mechanical aspects of the Unstable set. Whether used in casual play or kept as a display piece, this card captures the spirit of innovation that defines Unstable.
