I got a plat Kamara on auction for 43k (quicksells for 44), so using him for now.
Right now using just the base Lamar (also a quicksell) until something strikes my fancy. Keep trying to snipe my boy blue Joshy poo, but it hasn't happened :(
The past 2 years I've really used the launch window to snipe the platinum cards to build my team. People make a LOT of mistakes early, and I have gotten basically my entire team full of platinum cards for right around (or even under in a lot of cases) their quicksell value. Makes a nice starter team for cheap/free.
