I've looked in the forums, but I can't see any place that explains the function of My Precious, and when I add missing cards from a decklist to Needed, the price of the deck doesn't update as I remove those cards from needed. Help!
We are working on a tutorial, but think of My Precious as your card collection. You can use it to catalog all of the cards you own. Then, when you build decks with Deck builder, you can have the app go through your collection and every card in the deck that is not in your collection will be added to Needed.
Does that help?
Yes, thanks very much.
