Now that baton pass teams have been nerfed, it's hard to justify using scolipede outside of offensive pass.
Not at all my good friend, not at all. While LO cleaner scolipede is 100% viable, Iron Defense Scolipede is still just as dangerous as before when given even a single free turn. I have been running mono-BP since even before the nerf and have only benefited from the recent changes. Here is a very good replay showing just how powerful scolipede can be given a free swap in.

Here we have Gengar vs Latios. I win the speed tie and get a light screen up (at least I think it was a speed tie), allowing me to tank the shadow ball easily. I then set up reflect as he subbed. Taking advantage of the light screen, I swap in scolipede, who takes the shadow ball easily. Iron defense and passed to espeon, knowing I needed that light screen to beat gengar. I should've attacked there, but I decided to try to setup. A CM war ensues, but due to a lack of crit, espeon eventually won. Yes, espeon managed to beat stallbreaker gengar with a sub up, despite my earlier misplay. I then go on to kill chomp and got RKed by talonflame. I sent in scarfed terrak to threaten talonflame back out and lure in scizor. After a few turns of goofing off, I convinced his mega scizor to take the bait and kill terrakion, giving my latios a free swap in and duel screens. He tries to setup, but memento allowed latios to get scolipede in on a +0 megazor, who is total setup bait. I get +6 defense and subs and passed to zard-x, the forfeit came shortly after.
His only misplay was a perfectly reasonable prediction with megazor, yet scolipede and latios were able to come in multiple times and setup very dangerous sweepers who bypassed their usual checks. I made a much more serious misplay when I didn't kill gengar immediately with espeon and allowed my screens to wear off.
ID Scolipede is still and always will be a threat as long as he's legal, mark my words.
