Yeah, there was one; Don't have it right now, though. Could make it anew.
About the card thumbnails, back then I could programmatically get the "real" thumbnails (ie the ones used in-game) from the card ID, now it's no longer possible unless the hashed filename is stocked somewhere, which isn't the case in the current DB. Or unless they made the new hash names in a very stupid way. Which is also a possibility which I haven't tested.
