I forgot where I read it, but somewhere it tells you how many of certain rarities you can have as you get more cards. I know as you get more you can have more in your deck, but somewhere I read the exact number. None of the NPCs tell you. All the Triple Triad Master says is that initially you can only have 1 card with rarity higher than common. But somewhere else I read the exact numbers as you progress. Someone remind me where please?
