After playing pretty regularly for a few days I have fulfilled the meme. I moved away from Filia on point and swapped her for Valentine. The change really opened this team up and I'm very happy with how it's turned out. The current team is:
Valentine (H Bypass)
Robo Fortune (Theonite H)
Parasoul (Napalm Pillar)
Valentine on point gives me so many positioning and gameplay options that matchups are never boring. I feel like I have the proper tools to fight anyone. I can use Beam to run away, zone, approach, lock down, basically anything I could ask. Should I get hit, I have a DP assist to get people off my back. Val/Robo's biggest problem is that they both have fairly poor defenses but amazing neutral so it gives the team a glass cannon dynamic, but I have so many options that I'm not really bothered.
Robo / Parasoul is very fun to play. It's a zoning shell that needs meter to really pop off, but Valentine builds meter quite easily. In addition, Parasoul and Robo massively benefit from each other's assists. Parasoul gets a beam to help against zoners while Robo gets a DP to patch her poor defenses. I have considered running L Napalm shot instead of Napalm Pillar for some vs zoner matchups but I haven't looked too far into it (I'm still learning all my bnbs )
I was worried about DHC options with this team. Since Egret super can be PBGC'd through by most of the cast, all my safe DHC options cost 3 meters, not 2. With that said, I think this isn't too far off of other Val / Robo shells. I know Tyrone O Canada runs Val / Robo / Double and uses catheads to safely DHC into pressure with 3 meter. I don't have that option on this team, but I can DHC into Robo or Parasoul lvl 3 to get out of a pinch. That's not dissimilar to how I've seen Tyrone's team function. The returns on Parasoul lvl 3 are not as strong as Double catheads on block, but Parasoul on point is a perfectly acceptable position imo.
Another concern that might be unfounded is vial combo routes. I don't know how good vial combos are with Theonite and Pillar, but I'm optimistic about their potential. Putting poison on people and reseting them over and over is fun as heck, even if it's not optimal.
I've seen a combo with Parasoul that uses H Bypass, s.hk and Wall Bounces to do a lot of damage. Idk if that's optimal, but it will be fun to learn.
