I would like to see how versatile the world thinks card indexes are. I would also like to see how popular this is with other performers.

What effect would you set up if you were to carry a card index?
Would you stick to the time tested card from pocket effect or would you do something new that's never been done before.

Many years ago a group of guy were going to get together and watch a boxing match. They were betting, friendly betting no cash, how long the fight would go and who would win. It was a 15 round championship fight.
I had considered doing a pocket index with 32 billets. two sets of fifteen rounds with each fighters name in case of a knockout and two for decisions. I would have made my prediction and switched in the billet when needed.
I never did it but thought it a good idea at the time.

I'm sure there are other ideas for using indexes for other than playing cards.

You could use it to predict how many times someone will try to take a great method and turn it into a card trick, but there are not enough outs in a standard card index for that.

Apply your creativity and do something new.

Following the protocols,
