Secret Lair x Masters of the Universe™: By the Power of Grayskull!
September 14, 2026
Secret Lair x Masters of the Universe™: By the Power of Grayskull! brought the heroic side of Eternia into Magic: The Gathering, centering on He-Man and the allies who fought alongside him against Skeletor. The collection captured the colorful fantasy, magic, technology, and larger-than-life heroics that defined Masters of the Universe, with artwork bringing its iconic characters and imagery into the Magic universe. Its focus on the classic heroes of Eternia made it a natural companion to the Skeletor-themed release and a nostalgic collectible for fans of the franchise.
