Players can play any one card face-down as a “farm” during their turn, which is put in front of the player who played it and is turned sideways to pay the costs of cards.
The main idea of “Tarot Combat” is that both players start with 20 life, and take turns drawing a card, attacking, and playing cards. You can play special ability cards during the opponent’s turn. Also, these cards can be played any time. Instead, there’s 22 “trump cards” with special abilities. “Tarot Combat” is almost the same game, except there are less soldier cards that have special abilities. I posted the rules for “ Combat,” a card game using regular playing cards.
Tarot is famous for being used by fortune tellers, but they were originally used for games. A Tarot deck is pretty much the same thing as a regular playing card deck, except it has four court cards (Jack, Cavalier, Queen, and King), and it has 22 trump cards.
