Dai Vernon- Possibly the greatest card magician that ever lived.
Ernest Earick- A Creative Genius.
Flourishes-
Daniel Madison- Style and just a pleasure to watch
Dan and Dave- Started the flourishing movement (Pretty much

)
Now, I msut say something else though. Everyone is saying that Dand and Dave are the "New generation of magic." I seriously hope this is not true. What they do is not magic, it is eye candy. Now I'm certainly not saying we need to be in the dark ages where you need a table and an hour long story for every trick you do, but, I am saying that we do need tricks that envolve the spectator and actually have a purpose besides "Oh that was cool." (Which is the usual response I get when I do The Queens or Tivo 2.0). I think the new generation of magic should be some one like Daniel Madison- new tricks, that are quick and enjoyable but they also envolve the spectator and are fun for the audience.
I am in no way against Dan and Dave considering I love all their flourishes I am just saying that their magic leaves alot to be desired.
