Featuring the three Kalos region first partner Pokémon, the Kalos Starter Set Decks are a trio of Theme Decks each with a regular version and a deluxe version. Released on November 8, 2013, the Chespin Deck, Fennekin Deck, and Froakie Deck each include a rulebook, damage counters, status counters, a custom coin, deckbox featuring their respective Pokémon, and a code for the Pokémon Trading Card Game Online, allowing players to unlock the respective deck online.
Both standard and deluxe editions of the decks were released. The deluxe versions contain a Booster pack from the Black & White Series, in addition to the deck.
The Japanese release is much like the release of the Black & White Beginning Set, two simultaneous Deck Kits were released marketed at a specific gender. The contents of the two sets are largely similar; both have three Half Decks based on the Kalos first partner Pokémon Chespin, Fennekin and Froakie; both also contain the same assortment of game essentials. The major difference is in the design of the products and items themselves, the girls set advertised as "cuter" when compared to the standard Beginning Set. Each set also has a small number of exclusive cards, but both share a collective numbering system and set symbol. The Half Decks are further identified by featuring colored silhouettes of the appropriate first partner Pokémon.
In addition to the Half Decks, each Beginning Set contains damage counters, status counters, a custom coin, and playmat as well as how to play DVDs and manuals. Deluxe (DX) versions of each set were later released a week later on November 15, 2013. The DX versions contain the same contents as their regular counterparts in addition to a themed deck case, card sleeves, sticker sheet, notebook, and are presented in a metal case, but no additional cards.
Starting with this set, Pokémon of the player going first cannot attack on the first turn.
While this is the first set of the XY Series, filenames and urls relating to the Kalos Starter Set designate it as "xy0" compared to XY being represented by "xy1".
