Personal Comment: I sort of like this. Easy to do, although... I need to hold my right hand in a odd position during the main move. Otherwise it would flash. I guess big hands help with this one. The effect is clear and it has a fulfilling climax. I changed a tiny bit about the ending. According to the books, one of the kings would be put in the center and the remaining one would turn into an ace. It bothered me that one got treated in a non magic fashion. So I made both kings transform into one ace. Like an upgrade if you will.
