Let me chime in for a few moments...
I don't think that a trick has to contain new principles to be good. Very little is completely new anyway. Nor does it have to fool magicians. They're typically comments from magicians who want the next greatest thing.
However, that doesn't mean that they're completely wrong either, and there have been a few short but insightful comments about where you need to go from here. You've got a trick that, ok, isn't the most original thing in the world, but more importantly, it hasn't been developed well enough. This is my biggest worry about The Wire - if quality control isn't set strictly enough, every magi and his wand will be able to release mildly creatively but half baked ideas like Devin Knight, Jay Sankey and Kevin Parker have a habit of doing (although at least the first two release good stuff periodically).
You need to give your trick some meaning, some purpose. Since you're not introducing anything new technically, in terms of sleights - and that's completely fine! - what people will be paying for is the way in which you've combined existing sleights. In other words, the final trick has to become greater than the sum of its parts. Commonly, this is done by giving it a new presentational angle, using sleights in novel ways, or giving the trick meaning/direction/purpose. Again, not having new sleights or an original plot is completely fine - but something about your take on the effect has to containing something new; you have to have something to say, to add to the great body of magical literature.
I realise that this could be said of many tricks on the market. You'd be correct in pointing that out. There's a reason I've bought very little magic recently. But regardless, this has not yet happened with your trick, and for that reason I wouldn't advise submitting it just yet.
