Not saying that I'm totally fond of gimmicks and gaffs but it just proves that gimmicks can be so much more effective sometimes.
However, if you pick the right tricks and the right patter, it can just amaze spectators with just a deck of cards. As I've said before, I nearly never do gimmicked tricks but I still get amazing credit and I'm proud of it. I think my patter is totally suited and I try to make the magic happen in the person's hand.
[slightylyofftopic]Just yesterday, I went to my brothers workplace and their were no customers (football match) so I decided to do magic to the staff. All I had was a deck of cards so I just performed card tricks and although I was nervous, because I hadn't done magic in ages, I didn't mess up at all. In fact, I used a few VERY simple tricks like the DL transpositions and the ace assemblies. I did the preparation right in front of my spectator's eyes!

So... I've never had competition with other magicians lol.
