do we are talking about true magic, not tricks? meaning influing on real word events without using technical devices, almost directly, accompanied with some unrelated actions, silke spells, pictures, hand gestures, and similarly strange artifacts. do not speaking about calling mighty creatures from other dimensions, because this is cheating and may cost you.
the key point to understand is that our matter world everyday laws is quite delusion, though applicable at wide range of cases. origin of our existence is wave processes, our space and rigid objects is just a projection of the processes on holographic surface, like a complicated patterns on water surface. more details are here: my quora answer: What makes time, time?

wave processes in outer world and inside lifeform/brain are resembling each other, compatible and can match, allowing lifeforms to interact with outer environment. this interaction is confused and multistage, and not much effective.
what if we can directly project waveforms from our brain to outer reality? like small sound activating big camertone. all those spellings, gestures and pictures are certainly helpers to generate waveforms, because they produce some air, spatial or visual waves. artifacts can be amplifier camertone.
and also there is required a lot of training and knowledge to hook on outer processes with brain's imagination and shake these processes into desired direction. if you can imagine it, you can do it.
our technical civilization is very young, 200-300 years. and thousand years without hitech. why ancient people had no need for hitech? seems they had magic, which is gone several centuries ago. why and where it is gone? make a movie about this, it have a chance for success, scenario seed is here.
