Is it still possible to use the old classified deck by replacing some cards by the new ones ? If yes, could Corvus Belli tell us which objectives replace which one (for standard and extreme mode) ? Also, where can we find the symbols for each classified (the one used by intelcom (counterespionnage) ?
Half of the old deck is still in use... but the numbers at the base might vary. I would suggest to print the missions, and add them to the classified deck until the new one shows up. You would need only to add 20 entries, so pick half the copies and replace them with the new ones until you can buy the new deck.
