Still looking for an UU team or..?

Doesent even matter at this point idk how to build a team

Well in most competitive battles people use OU pokemon / Uber (if allowed).. I could advice you on a team if you like. Just PM me if you're interested and I'll talk you through 5 more pokemon.

Froslass is a really solid lead, however, I don't really know what you have available.

As for recommendations, I would either run hyper offense or a bisharp to prevent hazard removal and a spinner (if you need hazard removal for whatever reason).

A hyper offensive team is so solid offensively that your opponent is rarely able to defog and you already have frosslass to spinblock scarf drill(although not all that well to be honest). Try pokemon like thunderous, scolipede (pass or sweeper), talonflame, greninja, sharpedo, tornadus-T, terrakion, keldeo, halucha, latios, mega pinsir, mega charizard (x or y), etc.

Bulky Gyarados and choice band azumarill are useful if running a team with bisharp because of all the fighting types running around. Other than that, I wouldn't know where to start helping you with the rest of team building. There are so many possible options.
