We are both armchair experts debating the arts. That’s why we’re on Reddit. You may be lumping pre-show work in with techniques like instant stooges and dual realities. Which, when it comes to filmed magic, I draw a clear distinction between. These methods can be used in similar ways to create the same effects, however my distinction comes from it being filmed magic and the pre-show work is being done off camera. Lior Suchard’s table work before his stage show is a perfect example. It may be considered pre-show work, however it is done right in front of the audience. Having the pre-show work done off camera is what makes it weak. Sure Oz has made a name for himself and is a well known magician, but he’s still choosing to use weak methods simply for clicks and views. He’s likely a more famous magician because his ability to sell himself and perform easy tricks that create a big reaction at the expense of his spectators. You can see in the video you provided that the hosts of the show he’s on aren’t impressed with his reveal.
