I like the thinking behind this effect. It plays just as it reads, but be warned that there are a couple of bits of bold handling required. By "bold", I don't mean the sort of moves that aren't deceptive and risk getting you caught by a thinking audience... what I mean is, moves that tend to intimidate beginners, because they're concerned they won't be able to do them well enough to avoid detection.

A few things I don't like: the way the deck is gimmicked doesn't feel reliable enough to me. I'd be very worried about flashing the wrong thing during the performance. Using rough/smooth seems like a better idea, except that would make the next required move more difficult. The point is, this effect will require you to work on your handling and be careful with it.

I also think the manuscript should've stressed time misdirection more. It is mentioned near the end, but for the way the basic routine is structured, it really needs to be emphasized strongly. Without time misdirection, you run the risk of tipping the method.

I also feel like the manuscript skimped a bit when it comes to presentation. Jermay briefly and superficially references the storyline he uses, but it would've been nice to have the whole thing detailed, especially since this entire manuscript is just a few pages in length.

Anyway, if you're prepared to take the time to work on the handling required, this is a very strong effect that should get good reactions.
