No, Mr Wizard, they don't wear out. They can be lost like any card. It's nice to have a spare, and you get three for $15 (while they last)!

Ok thanks I thought maybe since they have refills they were disposable for reasons they loss their distorting properties over time.

I keep Eight Card Brain Wave, Ultimate 3 Card Monte by Michael Skinner, Double Back by Jon Allen, and Entourage by Gordon Bean in my wallet. I will soon be adding Dollar to Credit Card 2.0.

Powerball 60, Sleuth, Dream Weaver, Zoltar.

I always carry color monte (great story for a quick trick)/ 2 card monte/ 3 card monte/ quarter bite/ and some business cards (jay sanke has an awsome effect) with me. I keep an extra "business card holder" like wallet for all those. And with that a thumb tip and a few coins you can always have a good little show.

I just carry four aces which allows me to do twisted aces and DR daley's last trick.

I just carry some card wallets and do some packet effects

3 business cards, written on the back to perform colour monte

Positive Thinking by David Forrest

Its Daves take on Max Maven's "Positive/Negative" and only takes up half the size of a business card.

Place your prediction down, get them to imagine three coins take one, toss it in the air then call head or tales and of course it matches your prediction.

If your in a country with different shapes of coins as well as sizes then you can actually let them pick the three coins you start with for an extra layer of deception.

All you need is business cards and you can do so many great effects like stigmata.

I use business cards set up as Svengali deck and Invisible deck (just need raised lettering for latter!)

Your wallet as a peek.

I must say that I have Extortion by Patrick Kun, which is a very visual yet practical bill change and I also have Vortex by Dan Harlan. I then use Rick Lax's 2 card presentation.

Oh, I also have To-do Vodoo by Rick Lax. Great quick mentalism which packs small and plays big. That's what I think are the best tricks for a wallet.

I second To Do Voodoo. I always have it in my wallet. Also, Deckwavoque by RedDevil (from the ebook 777) is awesome and unlike KK only requires one card.

Another vote for ToDo Voodoo.

Here is a video of my performance of the effect: http://youtu.be/yQEXMKgPxfM

Also I love Dreamweaver.

I keep a QH or a 4C in my wallet.
If I don't get a hit, I go directly into some propless effects.
For the 4C I either use a !@#$* inspired by the material in Daniel Madison - Psycho, or rely on pure luck (mixed with some talk about the most common cards).

Heirloom delux , loops , all in my esp wallet so ready for most things

I keep Anthony Owens' Ultimate Oil and Water, and Powerball 60 in my wallet, but now I'm considering ToDo Voodoo!

If we are talking cards its colour monte, otherwise its zoltars stars.
