Each of the packs contain twelve cards, six of which are Holofoil, and each one focusing on a specific Pokémon LV.X card. All of the cards except the Pokémon LV.X were previously released as Promotional cards in Japan, the majority of which are part of the DP-P Promotional cards collection. They also include cards from the Pokémon Fan Club that were awarded over the course of the 2007-2008 season. Each pack also contains the rare Time-Space Distortion Trainer card.
Several cards from each pack that were Holofoil for their original promotional release are not Holofoil in the Collection Packs, as to further differentiate the two versions. Similarly, some promotional cards that were previously non-Holofoil are Holofoil in the Collection Packs.
