I had lunch with Kevin and Alex on Thursday; Alex handed me a deck to keep (thanks again, bro)! There's some really nice features throughout that deck. I'll tip you on one of them.
Take the tuck box and fold the top flap to cover the opening, but with the flap outside of the box, and hold it against the back of the box. The artwork on the flap blends in with the back art, resembling a theater proscenium. Originally they wanted to create a proscenium image for all of the card backs, but it would have made having a two-way design and making it look good at the same time very difficult to pull off.
