I'd then break it down into sets and then you can break it down into individual cards.
The collectors info at the bottom is like set number/rarity/card number, i.e
15C108. So you can take the 15 (which is The Hunters set number) and group all the cards from that set together, then all the cards that are multiple copies will automatically go to that set. From there, much easier to sort them by individual card.
That's what I'd do, at least. I did, actually, all my cards are sorted by culture and collector number. All my friends think I'm OCD cuz i also sort my CDs by artist in alphabetical order and then by release date within artists.
