I don't know much about Zoomancers but I'll give it a try anyways
So here goes.
I'll have to completely change your build, but keep in mind that is only my suggestion.
Skills:
Summon resists: max.
Skelly masteries: max.
Mages: max. (I'll explain after)
Revives: 1 point
Curses: max the curse that lower resis.
Bones: the rest on prison.
Well I think you can guess the strategy of what i'm suggesting. Lower resis your ennemies and keep spamming prison over them. I know this strategie sounds cheap or might not even work Vs people that use enigma but same goes for normal skellys. Zoomancers are not really meant to be duelers...
And I don't think a good Boner would lose to a Zoomancer, they'd kill all your skellys while staying in range of their melee attacks or teleing away when you come close or simply spear through your pack of skellys and when you run out of corpses to make skellys, that'd be the end...
