Welcome back to Orbit, it's great to have you here again! A lot has changed since our last journey. First, let's talk about what's the SAME as the 4th edition Orbit Deck.
For starters, the feel. It took me 4 tries to get the feel exactly how I wanted it. I knew as soon as I picked up the 4ths that this was the way I wanted cards to feel. We have managed to duplicate the quality of the 4ths and I'm not sure if it's just because they are brand new, but they feel just slightly smoother than the 4ths.
Again, this might be my imagination -- you be the judge. The cards are a crushed premium (Bee) stock, traditionally cut, and with a secret ingredient to ensure a unique feel just like the 4ths.
