That works, too. The Murakomo options are:
A) Don't go in (bB)
B) Slide in low (B)
C) Jump in high (fB)
The parenthetical buttons are how Quince's B would work. So since our game needs to have crossups instead of high/low, we need the fB to be a crossup thing for sure, instead of a high. So maybe you are right that it should just be "fake, left, right" as the three options.
So he'd need some kind of super that works with that. How confusing and awesome would V-ism custom combo thing be for Quince? If you're not familiar, here's a video:
What happens is you leave a "clone" that does exactly what you do, but a set amount of time after you do it. In SFA you could decide how long that window was (short, medium, or long), but maybe Quince can't, and he has a set timer for it. It could be such that everything he does in this mode causes very little hitstun and can't combo (maybe yes on counterhit) so that each individual action would be a mixup of some kind. That's probably a little too crazy, but it fits him flavor-wise for sure.
Another kind of super would be one that autonomously fires off a random swarm of "B" attacks (never the feint), but the actual Quince player can still move around and perform actions?
With that sort of move I'd kind of want him to have a short range teleport dash like Slayer/Bison so that he could easily shoot this off and then spam C over and over to really confuse the opponent into blocking the wrong way. bC = teleport backward, C = glimmer out and go nowhere ultimately, fC = teleport forward.
I imagine that Truth Geyser is an air B move that drops to the ground like Rook jC, but then fires up a wave of gold like a Captain Corridor or Power Geyser sort of thing, hehe. Still no ideas on air C, unless it's the same teleport move but he can use it in the air, too.
One other thing to remember about Quince's Yomi incarnation is that he has a megaduff Pilebunker like DeGrey. But I'm not certain he needs to have that really. However, that could be the "honest" frontal version of the B move, animation-wise?
