The current state of Jack-O fS (GGST Season 2)
Getting hit by far S still isn't particularly threatening, even on counterhit, but the new servant recall opens up a couple routes. At close range (e.g. when using fS as a frametrap) you can go into 2H and get a decent combo out of it, or cancel into 214P and link a sweep afterwards. Just taking the hard knockdown is probably the best move most of the time, but Jack-O can also go for a pretty damaging OTG. At long range (e.g. when using fS at roundstart or as a counterpoke) you just get one hit of 5H, but at least you get to set up a minion behind the opponent.
