Your 'master magic create a double cube' looks very nice and I have never seen it before. I am just curious whether this puzzle was ever produced and sold commercially or did you make it yourself?
Thanks, dude! I wish it was commercially produced! If it was, I'd probably be rolling in it by now. It's a puzzle I invented and build myself. I'm surprised you haven't seen it before, though... It's what I've been using as my avatar since I joined Twisty Puzzles.
