Performing magic doesn't necessarily break the precept but the kind of methods you use to perform magic may break it. There must be four factors involved in your action to breach the fourth precept. If I take your example with the four factors here,
Hence, the precept has been broken here. In this kind of situation I think we can use our intelligence to avoid such things from happening. Even if you lie to save someone's life, let alone entertain someone that's still a breach of the precept. From this action, there'll be good results by saving a life and bad consequences from lying.

I don't personally see any problem with it. Although what you are saying is technically untrue, in the case of stage magic the audience knows that the performer is using sleight of hand and that it's just a trick. It's no more deceptive than telling a joke or a fairy tale. Technically the words aren't true, but the listener knows that. Unless you are trying to convince people that you actually do have powers like some fraudulent faith healers do and stuff, I wouldn't worry about it.
