Thanks for asking about this Undertaker. I'd also love it if somebody could take a look at this. Basically there's more than 1000 cards (a 1/6 of the card pool) locked behind a DLC paywall. This isn't even a free game either... nor is it mentioned anyway that the DLC isn't just a short-cut to the draconian method that the game uses to allow players to unlock cards within the game. All of the DLC isn't even out yet and it costs between 150-200 pounds (250-335 dollars) to download it all which is beyond ridiculous.
Somebody released a tool to allow all Xbox users to modify their saves to obtain all of the cards (even stuff that's DLC-only but doesn't have DLC out for it currently) right after release. Hopefully something can be done for the PS3 version too.
