I donated $10.00 and got the the confirmation page where my transaction had been completed and noticed that some things looked different. Only one code appeared and it was called the "Conformation Code", I pasted this into the redeem code section in-game and it said the code was invalid. So I opened the email paypal sent me and used the receipt number and the game also said that was invalid. I have no other codes and am very displeased that I just donated $10 and did not received the reward codes I needed to complete a deck. I dont know what to do about this, so I went to the chat and asked around and I was told to come here and make a post about it to try and revieve help. I also have screen shots of the paypal conformation page and saved the email.
