Gonzo:Flying Mantis Kick, It's very similar to what Crane Style can do, maybe a new type of crunch is needed to make it new and different.
Black Paper Moon:- Iron-Arm Block: I like it, but I'm curious why you made it Combo-Basic. Making the DV bonus not count towards the dice cap is reasonable and has its own tradeoffs (there are several effects that bypass cover); it doesn't seem like the kind of thing that you'd need to restrict. The Charm by itself is reasonable, and only becomes really strong when combined with the Form—which seems fair. I'd have made it Combo-OK, since I can't see a compelling reason to restrict it.
Mouse:Leaping Mantis should be Reflexive, or you're fucked if you include it in a Combo.
Plague of Hats:Flying Mantis Kick As one action the mantis leaps and strikes// allowing it to be accompanied by a reflexive leap towards the target, putting the target within range// If it hits, extra successes count double for determining the raw damage of the attack
Plague of Hats:Not if your Combo is Flying Mantis Kick + Leaping Mantis Technique. Or if it's a Join Battle Combo.
