You know you're a redneck when- .... wrong thread....
You know you're a noob when you bitch because someone uses a Pokemon that isn't usually used.
(Got bitched out for using a Miltank to sweep some random.)
Like Hark said, I'd put it over Serperior. Ferrothorn tells a lot of Pokemon to take a hike, and when it's combined with Jellicent it has that nice perfect synergy thing going on.
The Sand is strong with this one. I would go with a Jellithorn core, since you're using Tenshi-boah. That way you can take speciak hits, set up hazards, give your team a fire/water/grass core, AND give rain teams the ole' middle finger.
