My guess is, whether you started magic today, or have been in the art for centuries, if your trick is mindblowing, they will put some thought into releasing it. Whether or not they have you teach it or perform it, would be up to them. But I am sure they treat the effects fairly.
They also won't accept a trick if the method isn't practical. Good luck, they probably get tons every day. And they don't accept a lot. Make sure yours stands out and is amazingly awesome.
