The Zacian & Zamazenta vs Eternatus Special Deck Set contains two 60-card decks that center on the Legendary Warrior Pokémon Zacian and Zamazenta and their clash with the Legendary Gigantic Pokémon Eternatus. Zacian and Zamazenta are included as Pokémon V in one of the decks, which primarily feature Metal-type Pokémon, while Eternatus VMAX is the focus of the other deck, which consists of mostly Darkness-type Pokémon. The two decks share a collective numbering system and set symbol. While all cards are reprints from earlier Sword & Shield Era expansions, some include new artwork—of note are the Secret Full Art prints of Zacian V and Zamazenta V, which feature their Shiny variants.
Each Special Deck Set also includes a pair of deck cases, a pair of coins, a cardboard sheet containing damage counters and Special Condition markers, a playmat, a pair of player's guides, a damage counter case, and a large card box.
