Patrick Redford is a great thinker in mentalism, and Description is a great way to check out his work.

PROS:
- Clever principle is very easy to understand and use immediately
- No forcing, fishing, peeking, or anything like that.
- Requires only a new deck of Bicycle cards, a pen, and one other non-magic thing you already have at home
- Video goes into thorough detail about the method and psychology and includes many options and bonuses
- It's an impromptu trick with cards that's not a card trick
- Virtually no reset

CONS:
- Would have been nice if the video included a performance. It's still easy enough to figure out, but there's one aspect of patter or timing that Patrick never actually explained.
- The box is examinable depending on which version you choose, but the longer the spectator examines it the more likely the method is to be exposed.
- Wouldn't work with most borrowed decks.

All in all, this is a great trick for the price, and a fine introduction to Patrick's brilliant work on mentalism.

This is not going to bring down the house, it's not going to be a closer. This is though a great trick which I have used many times already to amazing response. Fun to perform and simple. It will take a bit a practice and at first feels nacky but worth an evenings effort
