Dark Star Cards

Dark Star Cards are weapons that Ludwig von Koopa uses exclusively in Mario and Luigi: Paper Jam.

Appearance
Dark Star Cards seem to look like normal Star Cards, except their backs are purple. The fronts of the cards are never shown.

Powers
Ludwig von Koopa can use four different Star Cards, which need Dark Star points. Dark Star points are given to Ludwig every time he deals damage to the Bros, just like the vice versa.
