Mystical? I think the meaning of 'choice' is well-understood. I believe philosophers have reinvented the meaning so they can put it into their wholly imaginary framework of doubletalk.
If you mean choice as something external to whatever deterministic/indeterministic framework we use to understand physical systems, it is mystical. If you mean choice as in "I wanted to do something and then I did it", which is the commonly understood meaning of choice, there is literally no conflict with determinism.
