Interesting lecture notes from Jim Steinmeyer about the fact that not all tricks are the same and you should endeavour to perform good tricks, not junk. He expresses his point very clearly and very convincigly.
The tricks, on the other hand, are not exceptional: the best one (and it's a very good one!), is the "Four Envelope Test" that was already explained in Genii: it's a good mental effect. Next best one is the "Magician who fools himself", a great presentation for a principle from his "Impuzzibilities" books, where a card travels from one packet to the other while the cards are handled all the time by the spectator.
