The Deck Kit consists of two Half Decks, Garchomp and Charizard, which are featured as Pokémon and Pokémon respectively, as well as Pokémon LV.X. The kit as a whole focuses on the team of Sinnoh League Champion Cynthia as featured in Pokémon Platinum and Pokémon belonging to Team Galactic boss Cyrus. The levels of the Pokémon , with the exception of Altaria, match those of their in-game counterparts when facing Cynthia for the first time, while the Pokémon belonging to Cyrus bear no relation to those he uses in Pokémon Diamond, Pearl, and Platinum. The majority of these cards could not be found in the main expansion. Those that were not were added to the main set when the English version was made.
Like other Half Decks, the Garchomp vs Charizard SP Deck Kit also includes a rulebook, damage counters, status counters, and a custom coin.
