As for Tyranitar, I do love it as a Pokemon, but it'd be doing residual damage to all my other Pokemon as well, so, not a fan of sandstorms. He would be a perfect team member when I someday make a sandstorm team, though.
Not looking for a Baton Bass set here. I'm just looking for a walled team with some means of attacking.
Yeah, I looked it up, Heatran can't learn Stealth Rock, which sucks, because Heatran would've been awesome.
