It would be cool, if possible, to add an option similar to the one in the overview page where you can only see copies for deck-building regarding of the rarity for the trading settings.
For example i currently own at least 1 copy of every card up untill 1 star rarity, and right now i’m only intereseted in finding trade for missing duplicates from 1 to 4 diamond rarity, of course many times based on other promo card that i have or having luck on finding the same card but with higher rarity i receive many trade that i mannually check to see if i have just 1 copy of that card in deck building mode.
It’s not that i don’t want to do that but it could help other people to select more fine grained trade to propose/select.
