@Maaz Hasan That's like saying, "I'm thinking about making some things, what do you suggest?" "Carpentry." Technically correct, but not exactly helpful. I call those "Microsoft Answers".
@Jayq - There's a ton of stuff that fits these criteria. You're going to need to narrow it down. There's self-working card tricks, psych forces, certain types of readings, suggestion based material, hypnosis (don't do that unless you're in person, though), things like Train Tracking by Atlas Brookings, much of the material by Fraser Parker, Slim King has his Rochambo routine he does over the phone/on the radio all the time, stuff by Kenton Knepper, Peter Turner, memory demonstrations ... There's a lot.
I mean, just the title of the thread, "Verbal Magic" - I can do an hour long show using nothing but words and volunteers, and that's not even getting into hypnosis. What exactly are you looking for, and then we can help guide you a little more effectively.
