I think Arceus and Mew should be able to learn Rapid Spin. In fact, there should be a Rapid Spin move tutor. Here's some pokemon that should learn it.
Nidoking and Nidoqueen, since it says they're "Drill" types.
Poliwag, Poliwhirl, Poliwarath, Politoed
Voltorb, Electrode
Omanyte, Omastar
Mew
Dunsparce (it has a drill on its tail)
Seedot, Maybe Nuzleaf and Shiftry, but mostly because Seedot since its an easy spin shape
Probopass, since it can change direction with the mini-noses, and if you've seen Pocahontas, you know compasses spin fast.
Solrock
Lunatone
Regice, because if Avalugg can spin on the pointy bits, then Regice can too.
Arceus
Whirlipede, maybe Venipede and Scolipede, but mostly Whirlipede
Vanillish and Vanilluxe, for same reasons as Regice
Karrablast, Escavalier (It says they move fast, but they have, like, 20 speed. They need to use that somehow.)
Klink, Klang, and Klinkklang since they're gears and won't stop spinning in their animations
Meloetta
Carbink
Diancie
