Teammates for Arvis

So, I've already finished building my Arvis and he's ready to incinerate some Sigurds (even though he... actually can't...). I'm having some trouble deciding on some teammates for him. I noticed his page recommended Fae or other green mages, but I don't have any decent ones not in use elsewhere atm. Any ideas? This Arvis has the optimal build from his page btw.
