I think that Primarina actually has the chance for Serene Grace as its HA based on appearance, which would actually fit in with the gimmick of its signature move if it's like the rest of the status healing moves. Heck, for all we know, the starters' signature moves are going to be hovering around the 95 BP range and we'll be using them anyways. Besides, I'm pretty sure Keldeo still uses both Scald/Hydro Pump on its Specs sets.
Inceneroar looks pretty nice. Love the animations for it, seeing as how it personifies the drama of a Heel Wrestler very well with them.
Decidueye looks pretty good as well. I see Ghost as an improvement over Flying typing-wise and it'll still get access to Flying type moves because it's still a bird. My question is whether or not it'll be a Physical or Special attacker. Leafage is just an ember clone(vine whip wouldn't fit) and its signature move looks physical, but it's a ghost type move.
