I don't know if he got permission for this from Nick Trost. I assume he did.
If honestly
was important, this should have been marketed as a modified "8 Card Brainwave".
The
modifications have their place, but to me this is a blatant rip-off. The fact he does not show the
routine in the teaser is a red flag. Too many people would recognise it as 8 Card Brainwave.
The trick is based on a classic and is good.
