Blade Rondo is a card battle game from Domina Games for one or two players.
Blade Rondo Night Theater is a stand-alone expansion for Blade Rondo. It can be played on its own with basically the same rules as the original, or combined to expand on the base experience.
For the unfamiliar, Blade Rondo is a minimalist non-collectible battle card game where each player picks just seven cards per match. It also comes with a well-supported solo mode.
