I prefer 'pretend' magic. Where in a witch says she knows magic, and reads your hand. In reality she's just saying the stuff everyone wants to hear, i.e 'you will be meeting a rich man soon.' This doesn't mean jackshit ofcourse because the same man might kick her in the ass for not getting out of her way, but she still met him. 

Or perhaps something like scaring a man or mob by changing the colour of fire, simply throwing in some herbs or a concocted bottle of spirits and whazam! Blue fire. Fear me, mortals! ''Ooh, magic!'' But in reality it's science.
