Decent Team Comp?

My friends and I have all mastery 10nd a character. We only had 4 but found a jungle. Our team comp goes as follows

Support - Ares (Me)
Carry - Xbalanque
Mid - Anubis
Solo - Chaac
Jungle - Fenrir (The person we found)

For this team comp (for casual for now) what gods should we look out for? Is it decent?

Eh, casuals it's alright. You got to note that Chaac falls off late game and can be countered relatively easy by say a Aphrodite. Ares is just a beads baiter and so is Fenrir so by getting both of them you're guaranteeing someone is getting CC'd. Xbalanque needs to be fed to be of any use to you and Anubis well he's beaten out by everyone. His clear is only matched by Poseidon and Kukulkan and even they have some form of escape.

A decent team comp would probably be something like this:
Support- Athena
Carry- Hou Yi or Neith
Mid- Janus or Eset
Solo- Bellona, Tyr, Odin or Osiris
Jungle- Susano, Serqet, Thor and Hun Batz

Experiment and have a look around.

The meta does shift a lot, and I personally believe that Ares + Fenrir has a lot of potential due to how they burn purification and other cc immunity as sods mentioned. The weakest parts of your team though are Anubis and Chaac. They're generally considered to be rather underpowered gods, although Anubis has a reputation for pub stomping beginners just because of his insane damage. Some good alternatives for solo lane would be Bellona, Tyr, Osiris and other strong warriors. Some options for mid include Poseidon, Agni, Scylla and anyone else who can really use Ares' ult setup to destroy the other team

Susano.

I would say to have only 1 comp is really bad. It depends on game modes however bans and well counters will screw it up.

Like said in zilby's comment, however chaac is still pretty decent in that he is pretty safe and has the biggest sustain of all warrior (cause passive) however he isn't as good as he used to be.
