The Random Construction Starter Deck (Japanese: ランダム構築スターター スタンダードデッキRandom Construction Starter Standard Deck) is a Japanese-exclusive introductory Starter Deck that was released alongside the Space-Time Creation expansion of the Pokémon Trading Card Game.
Information
This Starter Deck is unusual as it contains a random assortment of cards, whereas regular Standard Decks contain the same pre-selected cards. This trend had been used in Japan with every first expansion in a new Generation and during transitional eras until the BW Era, with an exception to this being in Generation III, where it was implemented in part via Half Decks alongside Flight of Legends. The deck could contain any of the cards found in Space-Time Creation, including Pokémon LV.X. Additionally, cards from the Entry Pack, differing from the main expansion cards only by a lack of rarity symbols, could also be packaged in the deck.
