Give back the ability to view just the mythic cards in the deckbuilder

One thing i didn’t like about the new deckbuilder screen is that you can’t view your mythic cards without your non-mythic cards, at least as far as i know. While it’s not really a big deal, it would be nice if you could at least type “Mythic” to view only mythic cards, and i’m pretty sure that would be an easy change.
