Very nice. Very clean and professional. I would play around with the type a bit more. I find the way the letters overlap a little unsettling. But other than that nice job, and welcome to the forums.
It depends on what kind of magic you do, and what kind of persona you want to convey to your spectators/audience (For example, if you are an underground magician, then go with the black). But if I had to say which one,on the spot, right now, I'd say the white one. But that's not for me to decide. That my friend, is up to you.
