Dude... Talk about brutal attack changes.
If anything Goodra should keep rain dance and dpulse, bide could go away for a good water move or even rest if you want to get kinky, power whip is also an interesting tool in Goodra arsenal, Goodra also learns sludge wave wich has been criminaly under represented in the Anime.
Talonflame has steel wing brave bird and flame charge, obviously the two turn moves are a big no, razor wind is mediocre and solarbeam coming out of a beak is plain disruptive for the suspension of disbelief animation wise.
Noivern has acrobatics and boom burst, I could see him learning flamethrower and a dragon move but hurricane could be a stretch unless they keep both acrobatics and hurricane at the same time, let's face it, the animation in acrobatics was really well done and I doubt the animators would ditch it, heck Noivern also learns solar beam psychic and shadowball, we could see those on him as his appendages make the animation easier.
Hawlucha shouldn't get bounce if God bird aka sky attack is available in his skillset, seriously that's the most show off name and attack in hawlucha arsenal at this point.
Greninja won't get dig, they are really pushing double team and there is no way the animators would take that away, night slash replacing cut would be great though.
I'm still not sure what to think about Goodra with Bide. It was pretty iconic with it before, but it's such a situational move, and they've shown in the past that they don't like characters relying on such a gimmicky move like that for every battle (ala Ash's Snivy with Attract and Dawn's Piplup with Bide). So hopefully Bide will get replaced with something like Aqua Tail (a physical move that's boosted by Rain Dance), or at least Muddy Water. Power Whip or Sludge Wave would be cool too.
As for Talonflame, I won't be surprised if it keeps Razor Wind. I mean, it wasn't really that clunky with Fletchling or Fletchinder, so I think it would be fine. I do kind of hope it gets something cooler, though.
I think Noivern was still shown to have Supersonic? I might be wrong on this, but for some reason, I thought it was shown using Supersonic and Boomburst separately, rather than being an upgrade like Tackle to Acrobatics. If that is the case, I really don't think we'll see it get more than just a Dragon move, hopefully Dragon Claw or maybe Draco Meteor. But I could maybe see it getting Flamethrower, Hurricane, Dark Pulse, something like that in place of Supersonic.
Sky Attack would be cool for Hawlucha, but I'm thinking it might be too similar to Flying Press, which I highly doubt they'll drop. I'm honestly alright with its current moveset, it may have three Fighting moves but at least each is functionally different. I do hope they give it something to replace Karate Chop, though. Focus Blast or Stone Edge could give it range, as pretty much every Pokemon Ash has ever had has had both ranged and close-quarter moves. Alternatively, Sky Drop would fit its wrestler theme, but it might be a bit gimmicky.
And yup, pretty much exactly agreed with Greninja. I hope it gets Night Slash, but I won't be surprised if it just keeps Cut.
The events of the movie maybe set before the episode for all we know. Also they can always edit the movie preview or whatever to contain Goodra or 6th capture. However, it is possible that Ash won't get Goodra back or capture a new pokemon until after the movie is aired.
It could be like that, but it certainly wouldn't be following any prior precedent. A month difference between this and the movie is a big gap. We knew about Ash-Greninja and Noivern for months before they ever actually happened, it would be kind of weird for them to try to hide Goodra's return; that's the kind of thing they'd normally hype up. Still, I'll keep hoping for Goodra's return or a sixth capture to happen before then.
