AKA, Cova Nell and the case of the commas.
Apologies if this has been covered somewhere, but does Cova Nell's ability (adding extra die while revealing red manouver) only work on defense while defending against a primary attack? I would argue this is the is the case. Her card text reads: "While you defend or perform a primary attack, if your revealed maneuver is red, roll 1 additional die."
The way the sentence structure reads so that if you remove "defend" or "or perform" it still has the same meaning for the remaining part. If you remove the part about "or perform" it becomes "while you defend a primary attack..." A comma after "defend" would make it so that her ability works on defense no matter what she is defending against.
TLDR: Oxford commas are good. If you defend against a torpedo with Cova Nell, you're out of luck.
