It's not too bad has all his old psych forces of different cards.
And about three effects that look like they are psych forces however they sleight dependent. The Psycho deck can and will kill if you put the effort into the presentation.
Pairs has potential for one on one or small groups, you'd have to play it up and I plan on messing with the handling some.
The Psycho deck is definitely a killer if you put the work into it, it's something I might just play around with.
Since I already own most of the psychological forces through his other works I didn't get as much from the first half of the PDF, though it did remind me of some subtleties that I might use to try and construct my own PForces.
Considering the price I got my moneys worth, especially with the promo code (which if you didn't see you're out 2 GBP

)
It's not something for everyone (the risk involved) but for those who like the idea of linguistics (Anate, for example) then go for it.
