something that would be nice even if its just for the demo is to be able to sell cards, i have so many dupes because i cant find the spinner
well the lewd cards are unsellable unless you plan to have a way to be able to get more of them
for normal cards they can not drop below 4 and unique cards cant drop below 1
as for prices... try $5 for normal and $10 for unique so you need to sell 10 normal cards, 5 unique cards or a combination of the 2 to get another pack
