I was doing some card tricks at Fantasma Magic Store in Manhattan, and I was doing some flourishes in the same routine. David Roth and Simon Lovell happened to be there, and after the performance they told me that my magic would be alot better if I did it without flourishes. They said that showing that I had skill with cards ruined the effects(to some extent), and that my mentality should be more along the lines of a cheating card gambler. What do you guys think, is Dan and Dave's approach to card magic cheapened by the fact that they do flourishes? Or is it just as powerful with flourishes as without?
