>>51011978You missed XY03 where Ash trained Froakie to parkour off his terrain in order to battle fletchling.
You missed XY05 where he's training for Viola before said training is continued in 06, oh look at that, training that takes place over multiple episodes as Ash tries to figure out a strategy to over come a challenge, rather than just having them use a move.
You missed XY023 where Ash is training Froakie and Fletchling, and finally manages to have Froakie hit through Fletchling's double team, while the latter takes a direct hit and keeps flying. Oh look at that, training for aim and resilience.
You missed XY024 where Froakie and Ash begin developing Rock Tomb Tomb, an instrumental strategy he'd use against Grant and later Sawyer, oh look, training that not only leads into the continuity of the show, but is major enough to actually feature in the League
You missed XY074 where Ash and Sawyer train for Valerie
You missed XY076 where Ash literally battles MOLTRES with Fletchinder and pushes his limits so far to evolve and fight back the legendary.
You missed XY099/XY100 where Ash and Greninja where the latter evolved achieved AG for the first time, starting one of the biggest training arcs in the show
You missed XY118 where Ash and Greninja are physically training with each other, jumping in the tree tops to better align their bodies and minds.
You missed every instance where Ash and Greninja faced off against Alain, yes facing your rival who you've never beat is training.
You missed every instance of when Ash faced off against a powerful trainer and gained experience against them for a later fight, such as battling Korrina's Mega Lucario or Diantha's Mega Gardevoir
This isn't even counting every episode where Ash is doing some generic training at the beginning of the episode, which is the vast majority of your examples
That's at minimum 8 more episodes of training you skipped, plus all the other instances of Ash pushing his pokemon to grow.
