Thanks @epicwally, just what I wanted to ask about adding decks and inventory!
@Petschedesign, if the boxes of cards aren't already sorted, I'd highly recommend sorting by set, color, alpha before inputting. I just did this with over 4,000 cards and adding them to deckbox was super easy. Not only that, the cards I need are now easy to find (see pic).
Cheers,
