The Deck Kit consists of two Standard Decks, Leafeon and Metagross, and a CD-ROM "Pokémon Card Game Online" with an access number printed on a sheet. The CD-ROM and number allowed users to create an account at the Online Battle Server and play Pokémon Trading Card Game online with other players via the internet. For users with a Pokémon Daisuki Club account, signing up for the service also deposited 2000 Action Points into their account for use via the club's Action Point System. The user interface was built on Flash, similar to but more advanced than Pokémon Entry Battle Web hosted on the official Japanese card database before its move in September 2010. The Online Battle Service terminated at the end of August 2010 as planned, as all new content moved to the Pokémon Card Game Network site in preparation for the first Pokémon Card Game BW-era releases.
Like other decks, the Leafeon vs Metagross Expert Deck also includes a rulebook, damage counters, status counters, and a custom coin.
