These are the Official_Game-Pieces that represent the Battle-Classes depicted on the Game-Cards. They are part of a Game-System but are called upon by the Game-Variant played.
For example, in addition to StarArena_The-Card-Game they show your opponents what type of Battle-Class hardware you are playing. (i.e. What type of deck construct)
In StarArena_Arcade-Chess they are an integral part of game-play and represent Arcadian-Armies battling each other and have the Full-Scala of Battle-Classes on the board, even though no-cards are used in this game.
They are meant to be multi-functional collectibles and the Game-Variants ask for their in-game presence or not.

• TITAN: Oyagami (Ancestors.
