I've just had an idea of a game which needs to combine both players decks, but I'm not sure how to differentiate the cards so players can retrieve their own cards after the game.
It needs to be a method where players can't tell who the cards belong to during the card drawing stage.
I was thinking about transparent sleeves for the cards where players can put something unique on them such as a sticker or symbol, but I'm not sure if it is the best method. I'm also aware that some people hate sleeves.
Does anyone have any ideas for me?
