1-9) rain
10) tomohawk
though that above synopsis is true, i'd assume you want a more detailed answer.
The first thing to note is that while some CAPs are stronger than others, a weakness to any of them is a bad idea, because all 14 CAPs are in the top 15 most used Pokemon. The only mon that breaks this streak? Politoed. Be ready for a lot of rain, because so many CAPs abuse it - Tomohawk, Krill, Cyclohm, and Mollux most directly, though Necturna, Kitsunoh, and Syclant appreciate the mitigated fire weakness.
Definitely you'll need a hard counter for SubRoost Tomohawk if you don't want to lose every serious CAP battle, and i'd suggest not getting swept by Tail Glow Syclant or Shell Smash Necturna. those are the three most immediately threatening CAPs, although Cyclohm, Kitsunoh, and Colossoil are all around good mons that you want to be prepared for. Last on your list would be jas hail - it's very anti-meta right now so you should definitely build a team that's able to take hail with abusers such as heatran, reuniclus, syclant, and krillowatt.
OH! And don't use pyroak no matter what. he sucks :l
