Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I just battled someone with this team. It did well, but I noticed that once you lose Mimi or Vish, you can get swept by quite a bit. Sadly, that is not really changeable through what you have.
I guess you just have to make sure you keep those mons in the back while dealing with the threats...
Personally, I run sub over earthquake and Bounce over power whip.
But this set works well for what the team needs.
Other than that, I think for what the team is. This is a solid build.
