Secret Lair Grabs Castle Grayskull: "The Most Powerful Superdrop in the Universe" Turns Winota Into He-Man on September 14
Five Masters of the Universe-themed drops reskin Winota, Tinybones, and Sisay as He-Man, Skeletor, and She-Ra ahead of a September 14 release
By the power of Grayskull, Secret Lair has its next Universes Beyond crossover locked in. "The Most Powerful Superdrop in the Universe," a Masters of the Universe collaboration, releases September 14, 2026 on MagicSecretLair.com, per Wizards' official announcement.
Five drops, one Eternia
The superdrop is built from five separate Secret Lair drops:
- By the Power of Grayskull! (5 cards)
- Nyah-ha-ha! (5 cards)
- She-Ra, Princess of Power (6 cards)
- Allies and Enemies of Eternia (6 cards)
- Sold Separately (5 cards)
The reskins
Wizards' announcement confirms three of the marquee character swaps:
- Winota, Joiner of Forces ({2}{R}{W}, Legendary Creature — Human Warrior, whose attack trigger digs for a Human to put onto the battlefield attacking) becomes He-Man, Champion of Eternia.
- Tinybones, the Pickpocket ({B}, a deathtouch Skeleton Rogue that lets you cast cards out of an opponent's graveyard) becomes Skeletor, Lord of Destruction.
- Sisay, Weatherlight Captain ({2}{W}, who grows with your legendary permanents and can tutor legends onto the battlefield) becomes She-Ra, Princess of Power.
As with all Secret Lair product, these are cosmetic treatments layered onto existing cards — the rules text, mana costs, and legality of Winota, Tinybones, and Sisay are unchanged, so the reskins slot straight into existing Commander decks built around those cards.
Pricing
Per Wizards, individual drops are $29.99 non-foil / $39.99 foil, with bundles ranging from $149.95 to $334.99.
