As a magician I sometimes like watching card magic that takes technique but since its not about me rather the spectator,AND also me as a spectator I dont care much to see cards simply hopping around. And thats almost ALL you can do with pure sleight of hand.
Its look "here but oh wait now its here" but to me..it could be more magical.
Gimmicks provide a much needed kick to card illusions because in gimmicks/gaffs its not about the cards.
Its about what happens to them.A chosen card eerily rises out of the pack without the magicians touch..The printed pips move on a card(!)..So much incredible magic.
I dont like being credited for sleight of hand. I like to be credited for putting on a good show and making great illusions.
Either way,sleight of hand HAS to be incorporated anyway to the illusion. hiding the gimmick or certain movements to make it work. Gimmicks and sleight of hand arent at odds.Never have been
They are Interdependant.
