Japan gets a three-deck box built around Mega Feraligatr ex, Mega Dragonite ex and Mega Gengar ex: The Pokémon Company lists the "Special Deck Set MEGA" for 13 November 2026 at a suggested ¥5,500 including tax.
The box holds three ready-to-play 60-card decks, one per Mega Pokémon, each running two holo copies of its Mega ex. Around them sit coins, a playmat, damage counters, paper deck cases, player's guides and a storage box, so two people can sit down and play straight away. Dengeki Online describes it as an entry product for newcomers rather than a collector release.
Collectors should not expect new cards. The official page notes that some contents were released or distributed before, and PokeGuardian reports that nothing new has been revealed beyond the Mega ex reprints. Each deck adds one holo copy of each of its two pre-evolution stages, from the Totodile, Dratini and Gastly lines. All three decks also share staples such as Hyper Ball, Boss's Orders and Lillie's Determination.
No English or European version has been announced. The three Mega ex cards themselves are already available in English from earlier products.
