I have e1 Tribbie, e2s1 Robin, e0s1 Sparkle (166 spd + sunday lc), Welt (wind set 156 spd). Who will be her best 3rd slot?

btw the only reason I took e2 Acheron cuz back then Acheron really lack nihility supports, but nowadays with many new nihility character come out, is harmony character still better than other nihility support. Should I just go 2 nihilty for faster ult? Or dual dps with Ashveil is superior than Acheron with support

p/s: technically Welt could be sustain and I could shove Tribbie/Sparkle in their team, but I heard M.blade need healer, it that true or false?
