I prefer Claw Sharpen because it prevents HJK from missing and potentially allowing someone to OKO you where they normally wouldn't.
Also, at Bombkirby: I discussed that with my friend later... I think that maybe sub, or CM, but I feel a bit sqeamish just having Ghost/Fire... I don't know... what could resist that?
Actually I didn't know about this (I don't look at warstories much) until someone recognized my team and gave me a link.
