This is an amazing card change for people not afraid of practice. It should look as good live as it does on video. I say "should" because I am still far from mastering this. It is an experts move. It is based on a previous move that some people may already know. If you happen to know the move expect a week or so of practice. If you don't expect a lot more.

Kelvin does not mention it on the download but this is a good move to practice with Pass Trainers(or taped blocks of cards) The moves in this were so unique to me that the pass trainer has helped me build new muscle memory without worrying about controlling every edge of the deck. My progress is coming along quicker than I originally thought using this but I still have a ways to go.

The light at the end of the tunnel is that it truly is one of the most exciting color changes I have seen in a long long time. You start with one card and end with one card and the angles are really good. I definitely feel the look and angles you get with this change will make it well worth the practice!

As you can see in the video, it looks gorgeous, and the sleight used has a few other applications that makes the price of this well worth it (not that these applications are taught)
The sleight is, however, extremely difficult, as Paul Harris says in AoA: "you are now entering deep practice land. Only a few will survive. The rest of you will be sold as wax."

This is a fantastic color change. Very challenging and difficult for sure. I've been a card magician for a very long time and haven't found many moves that are hard but for some reason this one is extramly difficult. I do wish the explanation was more in detail. He doesn't do a bad job just kinda flies through the main move. More angles would have been nice. Overall great trick though.
