sweet lord! i will make a prediction (and keep it in an envelope on my desk) - this post will descend into madness...
ok - disclaimer time - these are my opinions, im not telling you to do this, just telling you my opinions and views
Ahem, for me, it goes like this: your character, why/how you do the things that you do (skills/abilities/talents/and so on), those two dictate everything else...sooooooooo.....
as an extremely quick example - you could say force a card on someone, but dress it as "reading their body language" to reveal the card piece by piece...(but its still "just" a trick)...
there is also a hybrid form of magic, called mental magic - this is a very fine line between the two...that line blurs more for some, than others...again, it's up to the individual to decide, and more importantly, the audience...
that is - bearing in mind the audience do not know what "mentalism" means for the most part. If you ask them who Derren Brown is, they'll say - "he's that mind-fiddler", "the magician", "the psychological illusionist", "NLP scrote", "the messiah"....they will also not know who corinda, annemann, dunninger and the rest are...
card magic is for the most part, external...mentalism is for the most part, internal...by that i mean magic is alot more visual than mentalism, mentalism is obviously from within the mind, whether thats a power you have, the ability to read someone or influence them that depends on who you are, and why you are...
i personally don't really like street-magic, whatever style is performed, so i cant comment on whether any form of mental-magic would fit in with street performance in reality (rather than edited down, mtv style tv shows), but again, character dictates everything else in my book...
so, in answer to your question, i feel that both branches of the art can be mixed, aslong as your character and abilites/talents allow that...have fun discovering what's what, whose who, and how's how...
