Secret Lair x Masters of the Universe™: Allies and Enemies of Eternia
September 14, 2026
Secret Lair x Masters of the Universe™: Allies and Enemies of Eternia brought Eternia’s wider cast of heroes and villains into Magic: The Gathering, showcasing the allies and adversaries who surrounded its most iconic characters. Artwork by Dimitry Burmak, Alex Horley-Orlandelli, Benjamin Marra, Stephen Andrade, Craig J Spearing, and Ed Repka captured everything from heroic guardians and warriors to sinister magic and monstrous strength. Its broad celebration of Eternia’s supporting characters made it a fitting companion to the more focused character and setting releases in the collaboration.
The total value includes bonus cards only if all are guaranteed to be included.
