It's a slight on the unfinished side like I can still continue even when the game's over, but I am very intrigued by the idea ! There's a lot of mechanics you could play around with here because of the shared draw deck and discard pile, such as cards that draw from the discard for a chance to get the strong card the opponent used, or sabotaging cards that you put back to the pile but has the chance of you yourself drawing it. Hold on to the idea this is definitely worth keeping.
