Um...Milotic, A-Ninetales, Glaceon, and Frosmoth get Triple Axel. No.
The description: A consecutive three-kick attack that becomes more powerful with each successful hit.
The animation shows the Pokémon going up in the air with a whirling animation around them, likely to allude to what a Triple Axel is: a jump in figure skating, For humans at least, you need speed and to get high off the ground...and you need to be able to do something with your entry to enable yourself to get a fast enough rotation.
Pokémon have every right to defy logic to SOME extent and it's not unfair to take some creative liberties which lead to departures from the original source of inspiration...but I think that there should be a limit - like, why allude to something if you're going to make something that, without the name, you'd have no idea what the reference is? Make something new or reference something more direct!
With this in mind, even though it'd be hard for a Pokémon like Sandslash, they're at least bipedal; let's give it to 'em. I'm not sure if the Primarina line should really get them, either - their back fins aren't really legs, are they? If you take "kick" to swimming, we can say their fins work, since they kick with their hind fin to swim. With this in mind, I'd say that between their front and back fins, they could somewhat make Triple Axel work in a way that Hitmontop would - the kicking limbs going on top, doing a more Capoeira-type Move. What are Frosmoth and Milotic kicking with, though? MILOTIC HAS NO LIMBS! Frosmoth's legs are TINY. Glaceon and A-Ninetales? Might be able to argue for them, but being quadrupedal with legs that go straight down from their body, it doesn't seem to fit very well.
I don't see the gameplay benefit of any of these Pokémon learning the Move, either - they're all Special Attackers and it's a Physical Move. Making a bit of a stretch logic-wise to make certain Pokémon better would make sense to me. I just don't see why any of these Pokémon would learn it, either from a gameplay perspective OR a logic perspective based on the Move description and inspiration. Froslass might benefit from it? But looking at them now, I'm not seeing any legs, so this also seems like a strange choice...but Froslass has equal Atk and SpA, so I guess this gives Froslass more of a STAB offence option?
That said, I feel like it's really fitting for Tsareena, given her theme of THE POWER OF GAMS; I think it's cool that she gets it. Weak to Flying and having excellent Atk, I think it could be useful to try out in competition, too. I'm happy about Hitmontop getting it, since their use of it would be pretty acrobatic and look super-cool. It fits with the Capoeira theme in my mind's eye, even though the Move's execution by a Hitmontop would be entirely different from how a figure skater would do it. Also weak to Flying, so being able to hit back is good here, like with Tsareena! Cinccino seems kinda random, but someone who's really cute and could totally skate seems appropriate. Technician (which Hitmontop also has) gives it some competitive potential as well, which I also like.
