By either the explanation video or the gimmicks. Granted the trick looks amazing like the demonstration video when done properly. The explanation video isn't that thorough though.

The deck with the gimmicks in it doesn't look normal. Also on the gimmicks I received the pips are a bit larger than a standard American deck of bicycles and the color is also a bit different. It's not that noticeable, a spectator probably never will but I noticed it.

The moves you have to use are not super difficult but not that easy either and takes some getting used to. If your going to have gimmicks in the deck you might as well have an entire gimmicked deck which would make the trick almost self working then just do a deck switch to clean it up.

This version requires clean up that involves getting the gimmicks out of the deck and out of sight without the spectator seeing you. Which is actually pretty well explained in the video. Perhaps better than the trick itself but not something I am a fan of doing. There are also some interesting bonus ideas in the video which I give them props for including.

I appreciate what Engblom has done here, it's a pretty original idea and I do understand that this trick came out of a challenge that's why it was created the way it was. It may be a good trick for some people but for me I'm not a fan of performing it.

The trick it self looks great like I said but for what you get and the poor explanation video I don't think it's worth $30.00 that's why I gave it 3 stars instead of 4.

Yes this is a parlor effect, you will need to be seated with a card mat to perform this. Frankly there are easier triumphs out there - this one is really for an experienced card magician that wants to fool magicians.

The method is very clever, The gimmick is not. It does require you to be tabled for a couple reasons I will not reveal. It is fairly angle sensitive. With that in mind it would play very well if you are seated and the audience come up to you. As far as being able to use a borrowed deck. A little research to make sure the spectator has the proper deck is also a factor.
