Hey guys, I'm going to join a local tournament in a month, it will use Smogon rules along with some rules added by them(no entry weather, no legends at all), so my current team has been pretty much fucked up by that(Politoed, Salamence, Cloyster, Keldeo, Ferrothorn and Scyzor), and I was wondering if I should rebuild from scratch, or if I could keep some of my guys and fill with new ones.

Anyway, team building help pls.
