Hi, I believe that I reviewed your last team on here. It must be a pretty good team, considering you've won the majority of your battles on Showdown, but I do have some suggestions:
Ninjask is a pretty good choice for a stat booster. A baton passer it really isn't. Indeed, it has a great movepool for the job, but it has extremely low defensive stats, making it an easy target for practically anything. Indeed, you can use Protect to get that Speed boost for whatever else you are using, but that's pretty much it. If you try Sword Dancing with it, it leaves it as an open target (assuming you are doing Singles, as there is nothing on your team that would be used to protect it). If you give it a Focus Sash, however, it will be a great way to set up for Baton Passing, but that will be its only use if it doesn't have any attacks. Even though Ninjask isn't the only thing with Speed Boost and Sword Dance, Scoliopede and Blaziken aren't very defensive either, so it probably isn't the worst choice.
Goodra would work way better as a wall if it was the one with Rest instead of Rotom. Its ability, Hydration removes any Status condition in when it is raining, so it will wake up after using Rest, maximally restoring its health. If you give it a Damp Rock, it will rain for even longer (if it is the one using Rain Dance), so with that, Goodra would be a really hard wall to stop. I've used this trick with Vaporeon before.
I must admit that I've never seen Rotom with Rest before. I don't see why you'd choose it for that, but I guess it would work alright. Lum Berries are also better to have than any other status-curing berries, but Rest will cure any status other than Sleep, so if you use Rest to cure Poisoning, etc., you'll have the Chesto Berry to wake it up instead of the Lum Berry being wasted to cure the other status. This could still be a consideration, though. I also wouldn't suggest having two Electric attacks in the same moveset, but it's pretty obvious why you would do that, having Volt Switch.
I haven't seen many people use Mega-Pinsir much. This is probably the best thing to Baton Pass to, which you already know. Its defenses are also pretty decent. Also, with its ability Aerilate, I would suggest replacing Close Combat or Quick Attack with Thrash, which it will get STAB from. I'm surprised that few people are using this one, actually.
Excadrill's moveset's a little strange. Binding moves aren't common enough for Rapid Spin to be of much use, and if you aren't using Doubles, Protect won't do much either. I would get these switched.
Breloom is in a good position, especially with Spore (how is this move not banned?!). However, don't expect it to save your team from Fire-types. Rock Tomb is not a very powerful move, and it isn't very accurate either, so don't rely on this as your last resort.
Other than what I've mentioned, I say you've got a pretty good team on your hands. The biggest problem is still, as mentioned before, your big weakness to Fire-type attacks, which 2/3 of your team is weak to. You might want to switch one of these Pokémon for something that isn't, because you shouldn't just rely on Rotom and Goodra to always be there, even though they are still really hard to get past. Even if you still have this weakness, I'd still say you're pretty good to go.
I hope this helps :)
