c.HP is pretty much my gameplay reason for Squigly. So Spiral and Copter over Dive and LnL, at least for Parasoul? I was thinking Horus Dive might help Filia more, but Spiral is still a good move and I don't actually know. I also heard LnL adds to Parasoul's combo damage.
I'd like to run Filia point, I've just done more research on Parasoul. I'm fine with any order though.
I've been out of the loop for awhile with this game, but to me and my oldschool sensibilities (haven't checked out the beta)
If you want to use filia>parasoul
Then filia>parasoul>bella seems like the most obvious choice:
You have a pick of assists to choose from:
If updo for filia, then L shot for parasoul, and cerecopter for bella.
If hairball for filia then H pillar for parasoul and cerecopter or H LNL for bella depending on whether you want lockdown or horizontal control.
The assists you pick kinda dictates your playstyle. With a dp assist you can kinda run around and bait the opponent into your assist for the easy confirm, but you lack range so keepaway can be tough to deal with.
With a lockdown assist you are mostly trying to bait your opponent close to you/running in on them then doing your confirm with an assist input that will confirm on hit and lockdown on block allowing a second or 3rd chance at a mixup. Once again though the problem is range as most lockdown assists don't have much.
Lockdown assists also give the opponent the ability to pbag and render themselves invincible to any mixup for a small duration of time, which really kills the lockdown strat if you primarily use it for blockstun mixups.
This is why H LNL is so good. It only hits once so it isn't super easy to pbag against for a long time, and it also has more range than most lockdown assist and it hits for really nice damage since its one hit it doesn't scale damage to bad by itself.
But taking it and another horizontal assist is probably not the greatest idea as they cover some of the same areas.
Other anchor assist that might be worth a try are Eliza with cr.mk assist since it hits low and is semi lockdown. If you go with that though I think it would be prudent to go pillar for parasoul unless you just want to be balls to the wall offensive at which point a LP shot and cr.mk assist would help you do that while leaving you virtually naked defensively.
Personally if it were me I would run the team with parasoul in front and then filia second snd Eliza in back with cr.mk assist.
With this team order you get parasoul with updo for easy defense and conversions and you get a little nice mixup/reset I like to do with parasoul plus assist that just becomes even more wicked if I have lockdown style low assist:
Dash jump d+MK and call assist. Depending on the speed of the assist you may want to call the assist just after you do d+mk. What happens is parasoul stomps on their head with a high and then the assist low comes out... Not only does it come out though, but it also crosses up... And hits low at the same time while parasoul is still in the air. Now parasoul can choose whether the assist crosses up or not by canceling the stomp into air tear. If she does then the assist won't crossup. If she doesn't then the assist WILL crossup and she can land and confirm into combo. It's a helluva mixup even from neutral.
The way I set it up as a reset is to do:
Cr.lk,cr.mk,st.hpx2, st.lp,st.mp,BHK xx L shot (the L shot hits them in air and puts them into hitstun as they are landing.
From there you have a stupid amount of choices from dash up into a low. Dash up into a throw, dash into a Flp high, dash jump into stomp high (the mixup that I just explained), dash stLp burst bait.
I ran this mixup against Australia and newzealand for 6 months with doubles LK bomber as my assist.
Hope some of that helps :)
