Yeah you can add Protect in OO.
I would also mention that Scolipede can be used as an early-mid game breaker. If you watch the video you'll notice that it's one of the big reasons that Axel pulled ahead of Cicada:
SPL is fun
In fairness Axel had the advantage of the set not really being well-known so it was a bit more awkward to think of ways to stop it, but notice that it takes advantage of a lot of passive Pokemon and still can be brutal after a boost. Some teammates appreciate the earlier brutality against Landorus-T as an example, so it's really a Pokemon that can function in multiple instances (this just depends on what you want Scolipede for - a lure or a cleaner).
With Magnezone I would mention that it allows Scolipede to hold off on using Hydro Vortex against certain threats. Consider that Scizor and Celesteela take a lot from Aqua Tail - and actually there are instances where bulky Swords Dance can lose as I noted in
this post because Impish Bullet Punch is incredibly weak and after a Swords Dance will only threaten with Stealth Rock on the field or if Scolipede got dented. I wouldn't call Magnezone a
mandatory teammate unless you really wanted to go for the late game cleanup with Scolipede.
I would mention Tapu Fini protects against status which can cripple a Scolipede pretty hard (well, burn mostly. Paralysis can kind of bust it a bit but +2 brings it about normal).
* Pokemon that are checked by Tapu Fini can give Scolipede an easier time setting up.
This line seems rather confusing to be honest.
*Playing around Hydro Vortex: Thanks to the 1-time use nature of Z crystals you can safe your defensive check to Scolipede via Protect or a switch into sack on your side. Without Hydro Vortex or Life Orb Scolipede becomes much more manageable. Do however note that gambling on a Protect or the sack bait could also be used agianst you thanks to Sword Dance.
I think what you can mention is that some of the checks and counters below in your threat list (i.e. Celesteela). Hard to really say since Scolipede is in a rather awkward scenario like Omastar is where (outside of Baton Pass) its only offensive set is a Z move. You probably could reference what I did with Omastar as an example
here.
Phasers should just be in Physically Defensive. You can probably mention Hippowdon since it can phase out the second set without any issues. Not sure on "residual damage" - maybe better to just mention that burning or paralyzing it puts Scolipede at a bigger disadvantage. Stealth Rock is definitely a problem for it, and I guess there's the potential Life Orb but it's really not something that should be used often with Scolipede. I'm sure you can figure something to write in here - just that status can harm Scolipede and that it does suffer from Stealth Rock as far as residual damage goes. Even though Scolipede can take priority moves at full health it's still pretty relevant to stop it if Scolipede takes damage the first time around.
* Taunt users: Thundurus,Sableye or Tornadus can taunt the BP set thanks to their priority on status moves and prevent it from doing anything.
No one is really going to use Prankster Tornadus as an example. The other two are fine.
Definitely a start of a basis for what it's worth, so we can at least get the ball rolling and we'll see what other QC members have to add here.
And remove Starmie as a teammate it's really bland as a Spinner IMO. I would rather mention that Greninja can lay Spikes for Scolipede if it really wants to go for the late game cleanup or regular Greninja punching holes for Scolipede.
