I want to be able to look at decks I could actually make with the cards I have. Is there a way to do that?

Yes, you can try the site http://www.shoeboxmtg.com. If your collection is uploaded in deckbox, you can copy that over to showbox and it will tell you how to build top tier decks with what you have. It will tell you how many cards you're missing to complete said decks
