A bunch of good guys and their old rivals, the Brotherhood of the Cat's Paw, compete for valuable artifacts from the city's mysterious district. In a card duel, you can try playing for both sides, as each offers different strategic options.
The game is played in three rounds, in which you add your own cards to selected stacks of mystery cards to compete for them. You alternate turns until one player completes a round. Then the round is evaluated.
Once the round is over, evaluate the three duels for the mystery card piles in turn. The player who has attached their own cards to the pile with a higher value than their opponent wins the pile of grey cards.
At the end of the third round, players add up the values of all the secret cards they have received. The player with the higher total is the winner.
