This update adds the 4th Expansion, Box Edition, Canadian Edition, and Holiday Edition to the game. I also created individual shared decks for each expansion, and removed the comprehensive deck (too big, too long a load time).
Hardcore CAH players are encouraged to create their own streamlined decks to make the game more enjoyable and remove all the lame cards. You can even build your own personal deck to draw from! Players will always draw from their personal decks before they draw from the shared decks.
