I have never tried to memorize a deck of cards, but I did spend some time improving my memory a few years ago using "The Memory Book" (http://www.amazon.com/The-Memory-Book-Classic-Improving/dp/0345410025 http://www.amazon.com/The-Memory-Book-Classic-Improving/dp/0...). I don't know if it made much difference in my scratch memory (i.e. remembering random things that occurred, or facts that I've seen), but it made a significant difference in things I chose to remember. There's an effort required to file away facts, but once you've gotten that system down it's quite useful. I use it for remembering things like flight confirmation numbers or license plates.
