I have a glitch where In the tutorial I can't get past buying the bronze 1 packs. I buy 3 of them, and it keeps saying 2/3. I could even get a 4th but doesn't help, and I can't close the deck manager because of it so I'm just stuck.
I think it's a bug that doesnt' count the cards you've equipped, only the cards you have in your inventory. So unequip any cards you have and if that doesn't help, maybe try again with a fresh save file (skip intro and it'll take you straight to that part again).
I found the problem, in the old file, for some reason it was making the packs only give me 3 cards per pack instead of 5 per pack. So i couldn't reach the required numbered cards
