Real or Fake

My friend told me that there were yugioh cards with the initials PCK, PCY Does anyone Know those packets' real names?

PCY/K = The PC Power Of Chaos games. Y/K mean, respectively, Yugi the Destiny, and Kaiba the Revenge. There's a third game, Joey the Passion (PCJ).

Each game had a set of promo cards.
