The King's Caste is a modified Tarot deck that was designed to answer this question: What if European Chess were a card game?
It is compatible to any Standard Card game, or Tarot Card game, yet there are subtle differences that allow for wider range of game play/design.
The 86-card deck contains the following:
16 cards in each of the four French suits (spades, hearts, diamonds, and clubs):
10 numbered cards:
8 pawns (value 1–8, #1 is hashed)
2 bishops (value 9–10, #10 is hashed)
6 face cards:
2 rooks (one hashed)
2 knights (one hashed)
1 queen
1 king
22 trump cards
