The booklet describes a different rule for the suits in the classic stacks (Si Stebbins or Eight Kings) such that the suits don't follow a cyclic pattern. I think the idea is simply BRILLIANT, and the method is easier than Osterlind's one. As a matter of fact, nobody will ever notice that the same value card appears every 12 cards, while the sequence of suits (alternating colours) is obvious. Some mathematical properties of the deck ("mate" cards 26 cards apart) are lost, but this is a minor drawback. To study and use!!!
