It's an interesting concept, but I'm not quite sure how turn-moving would affect the duel aside from buffing Selphon. Final Countdown, Swords of Revealing Light, and Pyro Clock of Destiny are the only turn-based cards that come to my mind. The timey-wimey soccer this set plays is fun, but I'm dubious as to its usefulness. What exactly did you have in mind with this?
