Is there a way to get a list of cards you are still lacking in a deck, like print the cards i have not added to my collection?

A long-standing request has been to restore the ability to let us sort by any of the quantity columns in the database. Once we can do that again, it will be fairly simple to see, though there has been no distinct feature to print a needs list.

I export to a spreadsheet, filter as needed, and print from there.
