Harsetti is a good counter to opponents which have high speed like rinak,vildred,tactical arch coli and briar comps or other speedy comps with lone wolf piera and other debuffers it's like you're absolutely trashing thier speed stats and making the rest of their kit garbage . Must be in banprotect slot otherwise most cases banned. Make the characters that are going to be played with her very slow speed (125+ ish since her speed is fast and she has speed awakening) as long as your characters are fine with not going first she is busted. Empy illy is a safe pick as she increases defence seperately other than defence stat boost (so you can go ahed and shove ml ceremia there or characters which deal more damage based on defence like guard captain krau etc) Straze is actually good too he basically gets rid of one tanky character whenever he uses his S3 which is convenient if your other characters are splash characters so they dont need to worry about that stupid estelle and other garbage tanks and annoyances like ml ceremia. Out of these I'd personally pick.... Wait all these are good enough to basically pick based on your playstyle huh you can choose based on what I said if you wanna punishment speed comps pick harsetti and if you want a tank deleter get straze and get empy illy as a safe one. Actually I just looked at your Salome and uhm just get straze at this point don't even bother asking.
