Topic name. Sorry if this has been asked before, I couldn't find a forum search feature.

Essentially I'd like to know if there's a way to filter for this, so I can know how many new copies of cards I need to buy when building decks. If it exists, is it also possible to filter in other ways, such as when the copies in decks and inventory is equal, or if there are one or more extra copies of a card in inventory?

Yes, in Inventory -> Filter -> Add more Filters -> Count in Collection -> Unused count

Thanks for the reply. Earlier I tried a combination of Unused Count and Count In All Decks and thought it wasn't exactly what I was looking for because it was including cards that I definitely have more copies of in inventory than in decks. But now I realized this was happening because it is applying these filters to each individual printing of a card.

So for example, if I own 3 printings of a card that I have 2 copies of in decks, all printings show up as 1 in inventory, are all individually less than the 2 copies I have in decks, so they all appear on the filtered list.

I guess my question now is, is there a way to make it so all printings I own combine into a single count, and then apply these filters to that?
