Posted this in the dead general so yea new thread I guess.

So I have this tournament thing coming up and the way it is going is one 3v3 singles battle, one 4v4 doubles battle, and one 3v3 triples battle. All with the same team with no changes allowed.

I have no idea how to even start building a team for this shit. Any advice? I am trying do decide which mega to bring. All megas are allowed except Mega Ray and Mega Gengar.

Part of me wants to run either rain or tailwind support for the latter two.

Part of me also wants to run trick room but that is risky as fuck.

And then when I start building for one format I am weak in the other one.

And team building advice would be awesome.
