I did try a deck like this for a while at various sizes. 56, 63, 70, and 100 (to have doubles of key cards). It was a fun idea, and I was able to pull it off as planned a few times. However, it was consistently unable to beat top decks and players. I'd be glad to share what I have, but I admit that in the end I decided that there just wasn't enough to make the strategy work yet.
