Is there a tool that already exists for this?
Here's my situation:
I have a lot of cards in boxes, organized by set.
I have three or four cubes I want to start building.
Some cards have been printed in multiple sets (big if true).
I want to make a list of the cards in a given cube, and all the sets that they've been printed in, to make it easier to go through old boxes. A local shop has binders organized by set as well. If I can go to, say, the UMA binder for 8 cards and not have to go to AVR, AKH, M13, M12, ZEN, AND JOU, then that would be lovely.
I COULD go to Scryfall for each and every one of these, but I didn't know if CubeCobra or someone else had this data in a database that I could pull from instead.
