Not every Pokemon I see on the list would be ideal Rapid Spin learners. For example, Miltank has that Scrappy ability to ensure it removes the entry hazards, which I think would be too much unless you have Ferrothorn (because it punishes spinning), but even then it can heal off that damage. Besides, it's more of a rolling attacker than a spinner, but that's just my opinion. I will list down Pokemon I would love to see with this move:
Glalie - Definitely! It is largely at a huge disadvantage in terms of usefulness compared to Froslass without Moody, because it has a huge movepool advantage over Glalie due to the benefits of being a Ghost-type. Glalie needs this move to differentiate it further, and with it, could function as a flexible Spinner + Spiker.
Voltorb/Electrode - Well, it's alright. Being the fastest Pokemon with this move (since Accelgor, Deoxys and Ninjask aren't listed) is quite beneficial, but what's even beneficial is surprising the spinblocker with a Volt Switch! Forretress can do this too, but Electrode packs a bigger punch with it.
Golett/Golurk - One of the only two Ghost-types listed, a Ghost-type spinner will make things interesting because it has the ability to threaten any spinblocker, and even better is that they are very powerful offensively. If Stealth Rock is added to their movepools, they're good to go.
Drifloon/Drifblim - Another Ghost-type spinner, so it will be decent for them, since they are also immune to the ground! Shame about their Rock weakness, though.
Venipede/Whirlipede/Scolipede - Another in which makes sense in general, and this would make Scolipede a better Pokemon, but the only problem is the weakness to Rock, which is a pity.
Shuckle - Basically, it now has another move to use despite its virtually non-existent offences, besides Knock Off.
Ferroseed/Ferrothorn - Although I would love this family to learn it, I am not sure if it will make Forretress even less viable.
Geodude/Graveler/Golem - Sure, give then something useful.
Lunatone & Solrock - Sure, let's get more Levitating spinners, even if both won't be really popular.
Munna/Musharna - Although they don't seem to be able to learn it logically, it would heighten their status as a supporter even more.
Jigglypuff/Wigglytuff - Another one that seems like illogical learners, but since they're already considered inferior than its pink fairy friends, why not?
Onix/Steelix - Would be awesome.
Magcargo - Even though it doesn't make sense for something like Magcargo to learn it, I think it would make it stand out more, simply because it makes for an unconventional spinner.
Snivy's family - Even though they don't learn Gyro Ball, I think it would be cool for this family to learn it due to their twister-based attacks.
Pokemon that shouldn't have this move:
Miltank - It has Scrappy, making the whole concept of a spinblocker moot.
Wormadam (Steel) - I guess it has to do with the other forms not being able to learn this move.
Metang/Metagross - They're already very strong, so perhaps they could do without it.
Dunsparce & Qwilfish - Don't see them logically having it.
Solosis/Duosion/Reuniclus - They're already powerful attackers, so I would leave them as they are. Besides, I think a Magic Guard spinner might be too good, even though people probably thought Magic Guard + Skill Swap was too good, despite having users with it now.
Omanyte/Omastar - Another case of "I think they're great that they could do without it". In their case, they have access to all forms of entry hazards AND Shell Smash.
Darumaka/Darmanitan - See above, except in their case, it's extremely powerful Attack.
Magnemite/Magneton/Magnezone - It's something I would actually love to see, but I am going to predict that the ability to trap Steel-types and spin hazards would be too good. You don't see natural trappers with this move for a reason, I think.
Bronzor/Bronzong - I imagine that they will be too good with this move because they are already Levitating Pokemon and possess a great support movepool.
Tepig/Pignite/Emboar - Doesn't seem like logical learners, so I guess not.
Typhlosion - Doesn't seem like a logical learner, even though a Fire-type spinner is a great thing to have (Torkoal is the only one so far).
Koffing/Weezing - Levitating spinner is cool, I suppose, but not quite a logical learner.
Woobat/Swoobat - Don't see them having it and using it well, especially when Starmie has a better type combination.
Lickilicky - In an effort to provide Wigglytuff with a niche, I have to say no.
Thanks for reading.
