The (CC) Card Group consists of many different NPC members who all excel at Triple Triad, they also hold very special cards which are only obtainable once/if you manage to beat them.
They also have a special requirement in order for them to spawn and they also appear in a certain order too. So make sure you have a good stack of cards before taking them on.
Below is a guide on how to trigger the side quest and who to play, where they are located and in what order they are available to play.
