The best way now is to find those effect you created and study them. Look at what so good about yours and the person who also created something similar. Than from there think of a way to create something better than both of this, then i would say you created something.
Just like the
An Unexpected Triumph by Magician Anonymous. I have seen people say they also created something similar. But the only good side is it has the color changing deck. So create something better than color changing deck. Maybe keep changing different kind of colors. Something like that.
