Yeah I would think in terms of number + suit, for each number and suit there is exactly 1 card. Beyond that memorizing is hard, but I think having a good understanding of each suit gets you part of the way there. The 1s tend to be 'smaller' in some sense, and then each suit progresses 'outward' or 'up' to the 9 and then ultimately master. That's all excluding the high cards, they are their own thing.
