Plz tell me how to sell cards.
Buy credits in shop then you can sell on market or go to my colection pick the card yoi want to sell and select sell to kate then you got a offer from kate you can accept then is the card sold
Sadly the only way that i am awear of is you must buy credits. I found the easiest way was to sms wat they ask for and enter the code. once this is done i dont think you will be restricted anymore throughout the game.
hope this helps
