"The EYE Brings the Battle to Life.
The unique combination of the PlayStation 3 system, the PlayStation Eye and innovative CyberCode technology evolves the trading card genre into a revolutionary gaming experience. Collect hundreds of cards and create a deck that comes to life as you strategically battle head-to-head, against the computer or against an arena of online players.
The game included a starter deck and a random booster of physical cards. Additional cards could be acquired via pre-built decks or booster purchases. Two expansion releases added additional cards, requiring purchase of a software expansion via PSN.
