The TRANSFORMERS Trading Card Game is a fast, easy-to-learn action battling card game designed for two players. Players build a team of TRANSFORMERS character cards and power them up with a customizable deck of battle cards. TRANSFORMERS character cards are huge – character cards in the AUTOBOTS Starter Set and Booster Packs are twice the size of standard playing cards, and can be flipped from bot mode to alt mode and back – and feature premium printing treatment on one of their sides. The deck of battle cards features Action and Upgrade cards to enhance TRANSFORMERS character cards. Players can add to their character card teams and battle card decks for full gameplay with Booster Packs. Each Booster Pack contains 1 TRANSFORMERS character card and 7 battle cards from a pool of 40 character cards and 81 battle cards. Each booster box contains 30 booster packs.
