Seeing as one hasn’t been started yet, feel free to post your cards that you have for trade or list cards you are looking for, specifically for CP4 Premium Champion.
Reminder that forum rules stipulate there is to be no selling!
Edit: I got all the cards that I needed from CP4, but I still got spares. Let me know if you need anything!!
