The Binder is the core feature of Reliquary. It is the best way to show off your vast Magic collection in a way that is fast and easy for you as well as anyone looking at your collection. Your binder is deeply integrated with the Deck Box so you can check to see if you own the cards needed to build your next amazing deck, and even mark the cards that are in the deck as "not tradable" so that they won't show up in your binder, but you'll still have a record of owning them.
