Each Charizard VSTAR vs Rayquaza VMAX Special Deck Set was packaged with two 60-card decks that focused on the Flame Pokémon Charizard and the Legendary Sky High Pokémon Rayquaza. The Charizard VSTAR Deck included numerous Fire-types, with the titular Pokémon supporting the Pokémon V and Pokémon VSTAR mechanics; the Rayquaza VMAX Deck similarly featured Pokémon V and Pokémon VMAX cards depicting its lead Pokémon and included a selection of Lightning-types. While all cards from the set were reprints from earlier Sword & Shield Era expansions, Charizard VSTAR and Rayquaza VMAX featured exclusive artwork. All non-power cards were also Mirror Holofoil and the two decks shared a collective numbering system and set symbol.
Each Special Deck Set also included a pair of deck cases, a pair of coins, a cardboard sheet containing damage counters and Special Condition markers, two VSTAR markers, a playmat, a pair of player's guides, a damage counter case, and a large card box.
