This is a simple card trick that will amaze your friends if you do it right.

Step 2: Now for the Explanation.

This is a trick deck of cards that you can buy from Wal-Mart or a magic shop. I got mine from Wal-Mart and they were in the toys section so you know where to look for them.

Step 3: Explanation.

The way the deck is a trick deck is that every other card is the 8 of diamonds like in the picture.

Step 4: Explanation.

Also the 8 of diamonds is a bit shorter than any of the other cards except the other 8 of diamonds.

Step 5: Explanation.

So if you are looking at the front of the deck you would flip the deck from the front back to see all the cards and to see only the 8 of diamonds you would flip it from the back to the front. There you have it, a simple card trick that can amaze your friends.
In other words: 1) Go to Wal-Mart and buy a trick deck of cards. 2) Read the direction that come with the deck of cards, which include a description of why the deck works the way it does. 3) Follow the directions to preform the trick.
Is preforming a trick in any way different from performing the trick?
My point was that this instructable was basically telling you to go read some instructions and follow them. It would be like doing a how to assemble a grill instructable: 1) Buy a grill at home depot 2) Take it home and open the box 3) Follow the instructions If I have instructions that I can follow, your instructable should be more than just givng the instructions I already have. For example, the instructions probably don't give you information on the kind of story you can tell your audience when you're doing this trick, or how to add a good flurish (sp?).
<p>LOL :)</p>
Also, I do believe it's called a svengali (sp?) deck. Named...after it's inventor.
One other characteristic of the svengali deck I have is that the fronts and backs of the cards have different adhesion factors. The front of the "trick" or duplicate cards are rougher as are the backs of the "regular" cards. That way, if you "fan" the cards, only the regular cards show. Other flourishes include being able to cut the deck reliably to regular cards. RTFM
