Cobalion is meant to take an EQ from Mega-Aerodactyl, and fire back with Iron Head. Pidgeot is my mega Pokemon, though I could see a different Mega could be used. Nidoking is meant to take special hits and fire back with Sheer Force boosted attacks. Yes, I know. My Magneton has Analytic. It's just meant to fire off powerful special hits, though if you think I should change this to Magnet Pull Magneton, tell me. Stakataka is a Trick Room sweeper that is guarenteed to get off a Trick Room unless hit by a multi-hitting, a status condition, etc. Kommo-o is my last mon, and it's meant to be a tank that fires off a wide range of coverage.
