Card Hero Speed Battle Custom is the third entry in the Card Hero series. The gameplay is a tweaked version of its predecessor, Kousoku Card Battle: Card Hero, in which players gather cards and use them to battle against opponents. Players can challenge either AI-controlled characters or real players online. One of the game's modes lets players use a unique deck each day, with themed decks that change based on the season or time of year, like special summer-themed decks during the summer months. The game features support for Nintendo Wi-Fi Connection and local multiplayer options.
