So if I understand correctly you want to make new cards that are obtainable ingame? I think I know how to do that, but I haven't tried it myself so it may not work. First you need to add entries for your cards in the \gameplay\items\def_gwint_card_items.xml. I guess this is the part you did already.Then you have to make entries for those cards in \gameplay\items\def_item_gwint.xml. I have only fiddled around with values here, never added something. But from what I understand here you specify the item icon and name (that you see in the shop and when you get the card as a reward), how many of the card you can obtain and some other stuff.I think the last step would be to add it to an ingame shop, which can you do in \gameplay\items\def_loot_shops.xml You should probably also create a new case for the name to int functions in \game\gui\menus\gwintManager.ws (they are at the end of the file). Then you can get the card through the console commands by name as well. Not sure if it is also used for other things.
