Hi Tom, thank you for your comments. I also questioned the same thing as you did. After showing it to some people, it is definitely more appealing to people who has an understanding of C&B like you said. For others, it is harder to follow but they do enjoy the illustrations and the surprise ending.
I did create a handling similar to an oil & water routine which is easier to follow but requires too many extra cards to make the packet trick reasonable in price.
Overall, i agree that this is definitely a nostalgic trick that is mostly for magic enthusiasts.
Will work on other handlings and share them here.
