Coins... Nabil Change
Cards... Royal Transpo
both are taught on Cultural Xchange.
My favorite trick is "Here then There," which is the first trick I learned.
It's simple, but hard-hitting, garnering excellent (and explicative-laden) reactions. I still perform it and perform it often. Moreover, David Blaine flabbergasted the Dallas Cowboys with it on national television, which automatically makes Here then There the bestest -- yes, bestest -- trick ever.
Cheers,
