The EX Battle Stadium was designed with quick and competitive play in mind. It contains two 60-card decks as well as 4 10-card sideboard kits, designed to enable players to adapt their decks to a 2-on-2 style match or improve it to a more competitive deck. All of the cards included in the kit are reprints from the first six EX Series expansions, though cards from EX Ruby & Sapphire, EX Sandstorm, and EX Dragon use the card design introduced in EX Team Magma vs Team Aqua, lacking the e-Reader dot code strips or "e" logo. The EX Battle Stadium also includes a two-player mat, a 16-page strategy guide, damage counters, status counters, and a game coin.
