The Star Trek Customizable Card Game is a competitive strategy game set in the Star Trek universe and produced by Decipher. Each card represents an element of the Star Trek universe, such as a starship, a character, a planet or space mission, or an event. Winning involves strategy both during a game session and before playing, through the preparation of an effective play deck, chosen from a player's entire collection of cards. Players compete by attempting to complete missions to score points according to a complex set of rules. The Star Trek: Customizable Card Game system includes several thousand cards, making each game session unique.
