I somehow have two Max Muncy 42 series cards and 2 Anthony Santander cards. First off before anyone says it yes it is my fault I picked duplicates but I don't even know why that is an option. If you already have the card you should not be able to select it since they are non sellable and you cannot exchange them. Secondly, I have seen posts on here with people saying they did the same thing and I was extremely careful when opening these packs and making my selections I honestly do not see myself making that mistake twice. I wonder if there's anything that can be done.
Submit a ticket to sds telling them the issue and pray.
