this change can be introduced in the future, but you can't change the purchase contract after the fact. you can give the money back to the people who thought they were still buying from the first 500k packs okay. but to print more cards now than was fixed before the purchase is fraud!

imagine you buy a playsation with 2 joypads and one day later the salesman rings your doorbell and takes one joypad away and gives you a cheap one just because he wants to satisfy more customers.
