Most of the moves marketed for cheating at cards are really impractical if you are playing with anyone who knows what they are doing. If you like card cheating, you have two options. First is to do what Steven suggested -- learn about cheating and work security at the casinos. If you want to go that route, check out Steve Forte's Gambling Protection Series. The other option is to do gambling demonstrations, showing people how you could cheat if you wanted to. Now, the key to recognize with gambling demonstrations is that you are rarely doing what you say you do (i.e. claiming to do bottom and center deals while really dealing duplicates from the top). That of course would be more in the magic realm.
