vengeful fighter > bold fighter on zelgius?

I got a +spd-res m!Grima, which is worse than my -atk+hp grima imo so I’m gonna fodder his VF.

I was thinking zelgius (+res-hp), but BF is his recommended B slot which i don’t have and L!tiki is taking my qr slot. would vf be good for a completely enemy phase build?
