With everything divided into tiers in the metagame, I was wondering what the best builds are. If I wanted to use a good Machamp, should I use a UU build or an OU build? There's even a VGC 2012 build that seems somewhat appealing.
Note: I basically need advice on building a team not so much for wifi, but local tournaments and battles with friends etc. --- Team Axis for Pokemon X and Y. Calling it now :p 01/08/2013
The difference between NU, RU, UU and OU is what Pokemon the set is based on countering. For example, an NU build won't take Salamence or Garchomp into account, as they are OU. In theory, the OU build encompasses the most Pokemon.
Do keep in mind that a VGC build is put together on the assumption you're using the Pokemon in doubles.
