Is there not a way to tag some cards as 'offensive' (1) to be played against an opponent and some cards tagged as 'defensive' (0) to be played on your own side?
I know that some cards are specifically designed to give an advantage to the CP or the Allies no matter who holds (and plays) them, these could be tagged in some way too?
I am playing a game as the Entente at the moment and the Central Powers just played 2 'Strikes!' cards on Germany. I don't think they effected them though as the last sentence didn't have a country name "..plays stikes on." rather than "...plays strikes on Germany." for example, but yes, would be nice to get this a bit tidied up.
"You, O English, who have no right to this Kingdom of France, the King of Heaven orders and commands you through me, Joan the Maid, to leave your fortress and return to your country, and if you do not, so I shall make an uproar that will be perpetually remembered! Behold that I write to you for the third and final time: I shall write to you no further." - Jehanne d'Arc, Orleans 1428
