I think it's a mistake to think that Inferno isn't a mimic. See 00:07:
"Fighting style: Whatever the fighting style of those under his control."
So I think he's a mimic that always has soul charge, and maybe his default copy is Nightmare.
Yay! Hopefully she'll be fast this time -- I'd forgotten she was even in SC4 after having a feel of how slow/unsafe she was (after maining her in SC3); of course, a top level player could still blow you away with her, using space and great launchers/combos, but it just wasn't fun for me.
Dope: timing. I haven't practiced for a bit, but IIRC that's what happens when you key 66 too early (before Natsu is actually -in- PO). Try going into practice mode and just practice until you can wait just long enough.
So, did anything happen at Frostheart's friend's place?
I talked to 8bit&more.
They're amenable, but maybe two many issues:
1. They have limited resources for setups now, apparently; I think they're down to two or three screens, which is apparently why they stopped holding tournaments...
