Do each of the starter decks have repeat cards, or is each deck totally unique?

Each deck has its own unique ship and a few cards the other decks don't have. Several cards (such as the basic Move card) are shared among all starter decks. Each deck is styled differently to complement the nature of the ship so each deck plays quite differently from the others. Since this is a customizable game the organization of the starters is subjective and meant only as a starting point for the player.
