Card Hero Speed Battle Custom is the third installment in the Card Hero series. Gameplay is based on a modified version of the previous installment, Kousoku Card Battle: Card Hero, where players will collect cards and use them in battle against other players. The player can choose to fight against computer controlled characters or human players. A mode in the game allows the player to fight using a different deck every day. The decks have special themes depending on when you play, such as special summer themes during summer. The game supports Nintendo Wi-Fi Connection and local multiplayer.
