Do you lose the option to use these over time or do they accumulate?
I know cards like Cotton and Demonstration go away if you don't use them.
I have 2 Sea Mines and i think One Submarine card in my current game at the moment. I think you get more as time goes on, but do you have to use what you have before a certian time period before they dissapear?
If i hold onto them, will i still get the same amount of "new" cards when they appear as if i had used them already?
Same goes for partisans and copperheads?
