The Starter Deck consists of 60 cards, 30 of which can be any of the Pokémon or Trainer cards found in both the HeartGold and SoulSilver subsets that make up the expansion (including Pokémon Prime and Pokémon LEGEND). The other 30 are a fixed selection of Basic Energy cards. Also included is a bonus promotional Gyarados card, which can only be obtained in the Random Basic Pack in Japan.
This is not an uncommon theme in Japan; random decks are traditionally released alongside the first expansion in a new Generation or during transitional eras. Exceptions to this include Generation III, where they were implemented in part via half decks alongside Flight of Legends; and Generation V, where they were not implemented at all.
This deck is similar to English releases such as the 2-Player Starter Set and 2-Player CD-ROM Starter Set, designed to introduce players to the new LEGEND format.
Like others, the Random Basic Pack also includes a rulebook, damage counters, and card list.
- Unlike the majority of cards found in decks in Japan, these cards have rarity symbols.
