Here is my reasoning. So people do one PLL to warm up sometimes, right? Some times they mix up their cube. Someone could get two Valk's and have one so it looks like it is mixed up on three sides, but on the other three, it is solved. They could have someone talk to the judge and when he/she is not looking, swap the cubes, show the solved part the non solved cube. The judge could see it and see the mixed up cube that they were using and call it legit. You also could do something where it is 5 moves mixed up, but looks fully scrambled and do the moves when the judge is not looking. What are your thoughts on this?
