My current Emerald team (rocks, haha.)
Gardevoir "Galactica" (Lax, Calm Mind, Psychic, Future Sight, Teleport. Don't worry, I'm not keeping Teleport for much longer)
Swellow "Raven" (Naughty, Wing Attack, Fly, Return, Aerial Ace. Same with Galactica, I'm nixing Wing Attack.)
Breloom "Shroom" (Adamant, Mega Drain, Sky Uppercut, Mach Punch, Iron Tail. I'm looking for a better move for Mega Drain.)
Electrode "Dynamite" (Modest, Thunder, Thunderbolt, Light Screen, Open.)
Swampert "Frankie" (Calm, Ice Beam, Earthquake, Surf, Open.)
Sixth one WILL be Ursaring. :D
Anytime I restart Emerald, I always end up choosing Swampert. I don't know why, haha.
