Some of these are one trick DVD's, others require gimmicks, others are just not what you need. First off, go buy this
NOW (not later):
CardShark Ortiz Set Volume 1 Thru 3 - DVD
http://www.penguinmagic.com/product.php?ID=S12342It's exactly what you want, and a
3-DVD set for $20 is nuts and will be sold out very soon. Ortiz is "punch-in-the-face" strong magic. Then pick up these:
Paul Gordon – Card Startlers (see his site, not sold here)
Bill Malone - On The Loose
Paul Wilson And Lee Asher – Hit the Road
More insanely strong effects, all with a regular deck of cards (couple of gimmicks/extra cards and such but few and far between). All those guys make a living doing card magic, so it's golden. I'm sure others will chime in with their recommendations.
