Just curious but does anyone have a clue how to get the second Fred/George card in the card game? I've opened a bunch of card packs and won the challenge matches against Snape, Hermione, and F&G (up to the max business share percentage) and I have every card but one of the Fred/George cards. Unless it is like a joke because they run the card selling business so they made that one stupidly rare to get you to spend a ton of money.
The other thing I was thinking of is it might have something to do with promoting their business by sending Hermione to work.
