[RATE MY TEAM] Revised team

[Rockycombo]

If you're looking to replace P2, Gigalith might not be a bad idea. That would give you an answer to any opposing weather, while syngerizing decently well with at least Garchomp and Celesteela. Though it might be counter productive with your Koko's Focus Sash. But Gigalith would resist Snorlax and P2's main STAB and has decent enough defense to survive all they could throw at you but a Belly Drum boosted High Horsepower (and if you throw a weakness policy on it, any other High Horsepower would just help you). Just a thought, though it may take some adjustment in your team.
