I was lucky enough to get 2 Nat 5s about a week ago, but these two just confused my eventual team comp even more, as I'm not quite sure what to do (currently lv36, with okay runes of mostly 4/5s, and a few 6s). Assume maybe 1 6* rune per monster (but assume I don't have the mana to get them above 9).

Right now, I'm working on getting my vero. I'm sure close; I just need to get the awakening essences for wind vamp and I'm done (all else awakened and max leveled). So I pretty much have vero. Knowing that I have:

Lumi, Chiwu, Xing Zhe, Bella, Shannon, Bernard, Tyron, and Vero.

I got Chiwu and Xing Zhe (both on the same day) about a week ago, but having gotten them just kind of confuses me more. Chiwu is a buff cleanser and speed leader, but bella can cleanse and tyron can speed lead too. Xing Zhe seems good (not that I have the runes for it but...), but I'm not sure if Xing Zhe should just be an arena-only monster.

I know Lumi can solo giants b10 with good runes, so she must be okay for giants b7, but idk.

So any ideas?
