Angeles Arrien describes the Magician as "The One who communicates" - people born under this card seem to communicate fluently without any problems - this regards all forms of
communication, like media,
non-verbal communication and almost anything that is related to information. Thus, these people excel as great speakers, media workers, artists etc.
According to my experience, I would refer to people born under Magician more as to "The Ones who play" - as it is depicted on the actual card - the magician seems to joyfully enjoy manipulating things to his own intentions, as he was playing some sort of a game. This, applied to communication, simply means that those people talk a lot and lie a lot - they try to manipulate reality with their skill of communication. These manipulations and lies are not neccesarily malicious, but these people seem to enjoy the confusion they create.
