The new Card-Jitsu game has not yet launched. But it will. Club Penguin said it is coming on November 17, but they didn’t say exactly when. They still have 17 hours of Club Penguin Standard Time to deliver the game. 
I’ll be waiting…
Remember that you will be able to buy special trading cards at the store and those trading cards will have special cards that can unlock cards in the online game. These will give you an edge in the game so if you want to do well you might want to buy some cards. Maybe.
