I just watched the episode and im starting to think he will keep Vacuum Wave. If you saw how he used it you can see its vital and cant be replaced by Aura Sphere. It was used as a mid range attack to help set up tackle (You know Meteor Mash is comming). Aura Sphere is a nuke not a set up move like Vacuum Wave that it is using as a set up to close the gap.
Guess he does not know Bronies are a thing. Also does not know boys love Unicorns and Unicorns are a very male thing ever hear of Pegasus well its one of the most manly thing from even ancient times and it is a symbol of a Hero even in China....
Poor Pikachu being target of jealous newbies. And never retaliating . Riolu has personalily flaws.
However, in Unova there was an opening that had all of Ash’s Pokémon at Oak’s lab including Squirtle and Primeape, but there was no Butterfree, Lapras, and Pidgeot, which tells me that they were released because if they weren’t and they are still owned by Ash then they would also appear at the lab. Nagandel only came back because the writers didn’t want him to capture another Pokémon to take its place and it came to help return the favor for saving its home. So Ash does things differently then most trainers would do so and until a Pokémon come back to Ash that was left in the wild that has no human care taker then that Pokémon in my book is considered release and I highly doubt we will see Lapras or Butterfree again.
