yep thats what i thought. I'll try to make it work
if it doesn't, back to 2 char team lol
wwayyyyy back (like first month or so of the game) i played valentine in that spot but stopped because my execution was shit and she didnt have a safe dhc. i dont really like her play style either tbh
My opinion for what it's worth:
The only good positions for squigly is point or second... I doubt you'd want her point in front of your parasoul so that leaves second only. Double isnt the greatest anchor anymore with cats being 2 meters and having no assist which puts more emphasis on squigly having to be very good on your team... She will have to carry her weight.
As far as how she plays its kinda like a double jumping flightless painwheel, Her neutral tools are primarily going to be double jumping alot while using random jhp for spacing and looking for an in. But her range is quite terrible.
The good news is that she's a good user of lk bomber if you can get in, though mk bomber is better for her cause of the range.
As far as safe dhc is concerned, those almost all have to be setup or done as blockstrings against good opponents so they aren't worth QUITE as much as in mvc2 and stuff, but are good in a pinch and definitely worth having. Sbo needs good setting up cause if you dhc to it to close... It will wiff and give the opponent a free punish.
You could also try the painwheel strategy that I use, only with squigly:
Trio team, painwheel at anchor, double in the middle:
The strategy here is to use car to dhc into painwheels install, making double the true anchor. In practice it isnt bad. And may work with squigly sbo in the same way though the dividends seem to be way less since squigly doesn't get an install... BUT, double is hella good with squiglys drag n bite assist. The only problem is the short range... But if they start out ranging you it's just car into squigly...which is why I like this strat so much with painwheel and dubs.
