No that's fine, part of the point of commenting is for feedback. And I honestly didn't want to remove Headbutt, Acrobatics, Aerial Ace, or Bounce, but that would mean removing an equal number of moves, and I want Mantine-A to have an arsenal of Electric Moves to use (plus Signal Beam, which makes sense flavor wise). Plus, I've removed what measly Attack Mantine has to boost Special Attack and a little in Speed. Mantine-A I guess is supposed to be a Specially bulky attacker, similar to Lanturn I guess, but I think he'd play that role well.Sorry to say this again but this submission may need some work, the first is Surge Surfer being an illegal ability due to the fact it is not 'released' yet, The second is the moves that "Would make sense but no one would use them", Most of them are pretty common moves that a lot pokemon learn (At least nearly all pokemons learn headbutt, and it won't make sense for Mantine NOT to have it), I am sure that the Mantine would still be able to fly (in their life at least while preying on shellfish) and therefor something like Acrobatics and Aerial Ace and Bounce would be needed, Ya know? Also normally, the moves removed would be moves that would not make sense to keep after such an "adaptation", and obviously there is not a lot of sense to remove them currently
It's true that Mantine-A could fly, though using that to attack physically, not so much. It could use moves like Wing Attack, but it wouldn't want to use them, since he's evolved to sacrifice physical strength to power long-distance attacks.
Should I still limit Mantine-A's new attacks just so he can retain the physical moves he would never use anyways? The problem is, I don't want to reduce it to just 6-8. I could probably get rid of Charge, Ion Deluge, Discharge (makes flavor sense, but Thunderbolt is better anyways. Still, it could be useful for mono-Electric teams, so I'd hate to remove it outright...), and Thundershock, but I definitely want to keep all of the others, making for a total of 9 new moves.
And I'd hate to remove Surge Surfer. It's perfect, an electrical version of Swift Swim that might give him a niche on Electric Terrain teams. A total of 150 Speed + Agility might give him a niche. Then again, it's not like he can learn Roost I guess, so mileage may vary...
I guess I might have to replace that with Swift Swim though, which sucks. Still, it isn't like there isn't a precedence where an Alola form gets a brand new ability, though it does suck that there is only one precedence.
Still, thanks for the feedback. At the very least, I'll think about it, and see what others say I should do.
