alright, my team is somewhat interesting. it uses three defensive/offensive cores, namely Celebi&Heatran, Jolteon&Gyarados, and Yanmega&Electivire. (credit to Yanmega for the yanmega/electivire idea) these pokemon not only switch with their partners but all other pokemon when nessicary.
Celebi w/ Natural Cure: Psychic, Energy Ball, Earth Power, Recover
Heatran w/ Flash Fire: Magma Storm, Flash Cannon, Torment, Protect
Jolteon w/ Volt Absorb: Thunderbolt, Signal Beam, Shadow Ball, Volt Switch
Gyarados w/ Intimidate: Substitute, Dragon Dance, Stone Edge, Waterfall
Electivire w/ Motor Drive: Earthquake, Thunderbolt, Ice Punch, Flamethrower
Yanmega w/ Speed Boost: Hypnosis, Substitute, Bug Buzz, Psychic
if you think they might use a status inflicting move, switch to Celebi; if you think theyll use a fire type move switch to Heatran, etc. Tell me what cha think of this team, feel free to say anything you think of it. Credit to danny for the gyarados moveset << Stahp multiposting to yourself. Also, I dont think mixed electivire is a good idea, try thunder wave to outbulk sweepers and cripple them. Celebi is too offensive, swap Earth power for calm mind. Take torment out for will o wisp on heatran. Theres more advice but I think you should figure it out.
