Opponenst are not actually negatively affected, becouse they always have the chance to discard and cycle the turncoata away to draw actual cards. The only thing this does is power up the confeatheration. If they want to hold the cards in hand to reduce the power of the confeatheration thats totally up to them.
Ofc i only had time to test these guys 3 times during the jam, and this latest iteration that i posted has not been tested at all. So things can and probably will change after i test more.
Ofc id love it if you test and come back to me with feedback! (Preferably on discord if possible)
