Magician

"Petunia did not want Lily as a bridesmaid, because she was tired of being overshadowed; Lily was hurt. Vernon refused to speak to James at the reception, but described him, within James’ earshot, as ‘some kind of amateur magician’."

- Description

A magician or illusionist is a person who performs illusions to make it look like real magic and as such tries to act as a wizard. A magician never reveals his tricks.

During the wedding of Vernon Dursley and Petunia Evans, Vernon referred to James Potter, a wizard, brother-in-law of Petunia and Lily Evans' boyfriend, as an amateur magician.
