What are the optimal Nicole teams for Chasca?

I've been playing a C1R1 Chasca for a while with Mauvika, Citlali and Bennett. I got C2R1 Nicole and replaced Bennett with her and she's a huge upgrade over him. I've been thinking however, is that actually the ideal team for her still? I don't have Durin to use with her, but I'm wondering if adding someone like Mona or Fischl might be worth it for the Hexerei bonus.

Anyone got some experiences to share?
