I need help putting together a team.

[SjoerdDN]

I have tried out a variety of combinations but nothing really seems to work out for any of my teams. I have a list of Pokemon that I have competitively ready with their most common builds.

It would be about a Doubles Team with normal VGC rules I assume.
