This goes better here...
My love for the Grass-type started with the TCG, way back in the day. I liked inflicting Special Conditions and passive status effects rather than dealing huge amounts of damage. Nowadays, Grass decks are getting a huge boost with Shaymin LV.X, so that's always good to see.
This is what I would use, in no particular order:
Ludicolo - Not only have I loved the pineapple duck since day one, Ludicolo is pretty much required to ensure I don't get DEMOLISHED by Fire-types.
Shaymin (Sky Forme) - Not because I want to, but because I have to - Infernape destroys me otherwise. Sucks that he's such a punk, though.
Torterra - Always had a spot in my heart for him. He doesn't get enough love.
Roserade - Very awesome Pokemon, and one of the only Grass-types who can use Rain Dance, which helps against the Fire-type matchup.
Breloom - He's such a punk that I can't not use him. He can beat anything he outspeeds.
Glaceon - Because Glaceon is a sexy beast (and resists Ice). I can't resist not using her.
Leafeon - Rain Dance, mostly. Also, Leafeon is decently quick and attacks physically.
The cool part about running this team is that no one relies on SolarBeam, so I am free to frolic in the rain as much as I want (and Ludicolo sure appreciates it).
