Hey man, welcome to the forums
I've been using these for a while, and, no, I don't believe these have a one way back. If they did I'm sure I would have noticed one by now.
I found out that guardians have a one way back!
Only way to tell is shuffle the cards.
And then flip through it like a cartoon flip book, and if you see a paturn jump, then find the difference in the paturn.
