in the sun...no comment.
though, seriously, sun starmie should still have a water attack, imo.
it's also helpful against stuff that usually tries to toxic you; you can set up on jellicent in the sun with it, for instance
Actually, everything I listed can tank a +2 Fire Blast under the Sun after SR, if they use specially defensive sets. None of them ever do, so my point is sorta moot, but j/s.slim, every time I've talked about NPNape, its been under sun. With sun up the things you mentioned can't take a hit from fire blast. I run the 40 attack evs and CC for killing 252 ttar. Without sun, yeah you're right.
Cloyster is prolly better left as a Shell Smasher
