You are a sleight of hand artist instead of a magician when you call yourself that and it is plausible that you use no gaffs when handling a deck of cards.
I have been reading through Daniel Madison's first lecture notes and through his patter he is constantly referring to himself as a sleight of hand artist instead of a magician. Its just a style thing and how you want to be viewed.
Do you want to be a magician and cause things to happen through "magic"? Or do you want to be a sleight of hand artist who promises to fool and does so? You don't have to stick with one, you you can "shift" who you are from performance to performance..."Hmmm, I want to be a magician today." or "Hmmm, I'm in the sleight of hand/gambling mood, lets be a sleight of hand artist today." Or you could switch mid-performance from an "SoHA" to magician and suddenly blow the audience away with something that "could not possibly be sleight of hand."
Its all your decision and your style, you just have to make sure that decision comes out in your patter.
