Slaughter the Dragon, Ha

From BoardGameGeek:

In an age of samurai and ninja, an evil dragon ravaged the land with storms and poison. To stop it, the local lord summoned warriors to slay the beast and return with its body as proof. But beware-cut the wrong spot, and the poison might claim your life instead. Slaughter the Dragon, Ha is a must-follow trick-taking game where the winner of each trick collects a Dragon Body token (positive points) and all purple cards played (negative points). The twist lies in special ninjutsu powers: one lets you swap hidden cards with a secret deck (Inverted Scale), another splits your hand into two parts for tactical management. The game ends after a set number of rounds or when someone reaches -100 points. A dramatic "Shoot the Moon" condition can reverse the tides, awarding +60 points to a player who collects all 12 purple cards.
