No, you forgot to post an essay (smile).
Just to get this out of the way, this episode was a first for Journeys, an actual Go-less episode, where he appears in NO capacity, and this kinda flushes my theory of his Project Mew thing happening concurrently with the battle down the toilet, but on the other hand, it would've taken away the impact/significance of the battle, so I'm not at all fussed about this.
Onto the battle, I do like how past Ash stratgegies have come to play in his battle, specifically from his gym battles in XY, firstly having Sirfetch'd destroy the Psychic Terrain with Fury Cutter, like how Hawlucha destroyed Trick Room with X-Scissor. Secondly M-Lucario sensing Mr Rime's movements is similar to when Frogadier did so trying to hear the movements of Ramos' Gogoat.
Leon's Dragapult I will admit put in some good work on Ash's team, taking out M-Lucario, though Ash kinda messed up leading up to M-Lucario's paralysis, though he wasn't to know that Dragapult is part Ghost when he declared the use of Reversal. Not only that, Dragapult also did a number on Dragonite and Dracovish and it didn't occur to me that this was the first time we had seen the secondary effect of Dragon Tail in the anime. I do want to know what this unknown power Dracovish awakened was, that in itself was jammy and borderline DEM. I did like the way Dragonite unalived Dragapault though, it was reminiscent of Charizard's Seismic Toss (I miss that move) and I also like how there were three beams of light when Dragapult returned to its pokeball.
All in all, this was a good episode, and even though Ash is up on wins (and also being the first to unalive more than two of Leon's pokemon), I say that Leon probably still has the upper hand considering all of Ash's pokemon have taken some damage, whereas Leon has two pokemon that haven't battled, and Cinderace who has taken little, if not no damage, and when Leon says this, I'm reminded of the battle between Ash and Paul where upon Drapion's unaliving, Ash's remaining pokemon had taken damage whereas Paul's Electivire was coming in fresh.
