The two High-Class Decks, the Gengar VMAX High-Class Deck (Japanese: ハイクラスデッキ ゲンガーVMAX High-Class Deck: GangarVMAX) and the Inteleon VMAX High-Class Deck (Japanese: ハイクラスデッキ インテレオンVMAX High-Class Deck: IntereonVMAX), each comprise a fixed selection of 60 Holofoil cards and feature their titular Pokémon as Pokémon V and as Pokémon VMAX that depict their Gigantamax form. The two decks also support either the Single Strike style or Rapid Strike style mechanic and come packaged with a player's guide, a coin, and a sheet containing 36 damage counters and 2 status markers. A Secret Full Art version of each deck's Pokémon VMAX also had a chance of being enclosed. It is estimated that one in four decks included a Secret print.
The Gengar VMAX & Inteleon VMAX High-Class Deck Double Box (Japanese: ハイクラスデッキダブルBOX ゲンガーVMAX&インテレオンVMAX High-Class Deck Double Box: GangarVMAX & IntereonVMAX) was also available from retailers on the same day. It includes the cards from the two High-Class Decks, the player's guides and the same two coins, plus a set of acrylic damage counters and status markers, a damage counter case, and two alternate art S-P Promotional cards: Empoleon V, and Tyranitar V.
The decks and double box were subsequently released in South Korea on July 7, 2021.
