Lots of good material can be found in Nelson's four-volume Sensational Mentalism series. Much is by Nelson himself, of course, but there are plenty of contributions from the likes of Al Mann, Bob Tripp, Steven Minch, Jack Dean, Syd Bergson, Bob Mason, Arthur Setterington, Phil Goldstein, Bob Parrish, etc.
There is very little with playing cards.
Methods are never dated, so I see no reason why these effects wouldn't play as well as they ever did (unlike, say, Nelson's many books on readings, where although the methodologies are fine, the readings themselves are quite dated).
Volume 4 is probably the best of the set, so you might want to get that one first, and see if the material appeals to you.
