Does any one know how to change the drop rate of certain cards in Galactic War and how to add prerequisites on what cards appear???
Each card (ui/main/game/galactic_war/cards/) has a deal function that returns a chance; you can think of chance as how many of the card are in the deck (500 is a common card). Chances are with replacement, so picking a card doesn't make it less likely. There are exceptions, notably slots and subcommanders (gwc_minion) which use the keep and discard functions to modify their probability as they are chosen or not chosen. I believe all the dealing is done when the war is started, which makes most of the things you'd want to do with prerequisites difficult. I suppose if you shadowed out some core routines, the behavior could be changed.
