yes, I will share the method. I was able to encode a 12 word bitcoin seed in the first test. By that I mean 12 numbers, each between 1 and 2048. All that with only paper, pencil, and dumb calculator. With this method I can fit in maximum 17 words. I want to see first how many more I can fit into the deck. Then also think more about how to encode other things.
When decoding, you need second deck of cards, which is in a standard order (not shuffled). That is for counting card positions. Only that one is being worked on while the secret carrying deck stays put.
