Mental Magic - Yes. Mentalism - No.
I don't object to the use of a deck of cards in mentalism, but that performance was mental magic, not mentalism due to the kicker reveal ending (what psychic power of the performer explains that?) and what I presumed happened before the camera started rolling (did someone say "pick a card?").
Phil.. I mean Max Maven has some great routines using playing cards. The better routines use handwritten index cards or ESP cards or Tarot Cards. The difference is that the audience views cards as magician's tools and magicians do tricks.
If you perform that effect often enough, you will probably get to the point where you don't need to force the card - especially if you tell the person not to react at all when you say the correct color, suite, etc. Saying that forces them to consciously tense up when you as it - watch for their eyes to move to their right as they think about not reacting and their lips to tense up (as if they are thinking "don't say anything").
Perception of reality is a selection of reality which results in a distortion of reality.
