Build decks with owned stock / collection

[RmenaLopez]

Hi! I'm loving the app so far, but I was wondering if you could support deck building from owned cards. When building a deck it would be nice to be able to change the "source" where the cards are being pulled from, so that I can search only in my library / stock.

btw, if you're looking for contributors I would love to help! I have some experience with Java web development, but I would like to learn and help if able
