If he's performing to a group of real people, I wouldn't recommend this so much...
Some tricks I can think of off the top of my head are:
-Stigmata
-Culligula Triumph (if you have been into cards for 4 years...)
-Five Speed
-Hofsinzers Aristocrats
-Paul's Bill Comes Due
-Finger Flicker
-Criterion or Recharge if you have a good ClipShift
These are just some of the things I perform regularly, and I have been into card magic for 2 years, so with double the amount of experience as me, you should have no trouble with these effects...
Why not bring Sponge Balls and Rubberbands along too? There is plenty of easy and hard-hitting stuff to do with these. People will get tired of the cards, trust me...
Hope that helped.
Good luck my friend!
All the best,

Thank you very much for all of the ideas I really like Hofsinzers Aristocrats. I'm probably going to use this one thank you very much.
