Out of usual archetypic teams, you an try building Arts variant around your Nero with Hans and support Tamamo / Waver. Won't be fastest, but comes packing some good survivability.
Could go Quick with Medusa / Alexander / Ushi and Hans with support Jack. Or just Crit, with Nobu and Hans with support Jack (this team should hit hardest of all three on crit turns).
...Notice the common trait here? Hans is *that* good.
Cu Chu Train, with Cu, Proto Cu, CAHassan and Marie can be interesting survivalist team with all them having three hit dodge / invulnerability, but clear speed would be lacking.
Siegfred + Georgoios combo is one good way to utilize Siegfred Ant-Dragon buff generally, via George's trait-applying NP.
