The Decktet is a deck of cards with suits, ranks, and named images. It is structurally unlike ordinary poker and tarot decks, meaning that you can do different things with it.
This looks very cool and makes me think about the SeaFarers game.
For each suit, there is an Ace and a Crown. Between them are other cards numbered 2 through 9. These each have two suits. For example, the Market is a rank 6 card with suits Wood and Knots. Suits are not repeated at a rank, so there are three cards of each numbered rank.
Quite cool. I like them. Will have to download it and print me out a copy.
