I still don't get why some of you want him to get Mudbray/Mudsdale.
Don't you think him having only six Pokemon, and two of them being Rock and Ground will be boring? They're not that different from each other. They share pretty much the same advantages and disadvantages, with very few differences.
If he was getting reserves, it'd be fine. But he's not
Actually, since Tapu Koko switched Fighting Z move with Electric one, i doubt Ash will catch a Fighting type.
Or it's a sign he isn't getting one anytime soon.
Neither Litten, Rockruff, or Rowlet can learn Fighting moves so the crystal would just rot. Meanwhile they'd have some time to go if they wanted to give him Electrium legitimately.... but what would be the point? They have two Pikachu ones they'd need to show off at that time.
I've written off Passimian as a possibility long ago, even though I would have wanted to see the lemur with Ash. But Jangmo-o is still a possibility if they're waiting until Poni to debut it. That would definitely be over a year based on the current pacing, maybe close to two.... though Poni will have to come faster if we really are getting Switch's game next year, it's obviously going to be the next generation so Sun/Moon has to end by then
