Maybe I need to rewatch parts of Ash vs. Sawyer but I've always felt that the first half was less engaging. I'll give points to Sawyer for the plan to shut down Hawlucha completely with Slaking + chopping down the trees with Aegislash, and a few to Ash for making use of the trees and Electro Ball in Clawitzer, but I do think the Talonflame segments were pretty boring.
I attribute the big strategy play from Ash to be in the second half anyways since that's when Pikachu vs. Aegislash was resolved. The second half is mainly animation focused indeed with less focus on strategy, but the tidbits on Noivern using echolocation in the smoke to locate Salamence, and Sawyer being ready for that is good, along with Sawyer paying that in return via using Slurpuff's smelling abilities in the smoke.
Overall, I think what the fight does well is demonstrate Sawyer's strengths and weaknesses - good when he's prepared (Slaking vs Hawlucha, being aware of Noivern's sensory abilities while also using it in turn with Slurpuff) while not being as strong when unprepared or faced with something he doesn't understand (Aegislash moment, losing to Goodra who he's never seen). I also don't really have too much issue with Pikachu going down - mans was tired after taking 2 Pokemon out. So that's why I favour part 2 more than part 1.
I think all of Pikachu vs Tyranitar was good strategy with the immediate taking out of the sandstorm, hitting a soaked (not the move but physics still apply) Tyranitar with Thunderbolt, making Stone Edge a projectile with the tail and Pikachu countering back. There also was some strategy with Noivern's echolocation and whatever the heck was going on with Hawlucha. I got nothing for Talonflame vs Unfezant but that goes in the great animation category, nor do I have too much for Pikachu vs Metagross asides from "jump on Metagross". In part 2 there was still some good with Pikachu using Iron Tail on the ground to put up a sand wall, but I think some of my "strategy points" go into Ash-Greninja vs Mega Charizard X because of innovative use of Water Shuriken that we really haven't seen much of such as using Water Shuriken in the ground to counter Blast Burn and using Water Shuriken as a melee weapon vs Thunder Punch.
Overall I think there was good strategy in Ash vs. Alain, but it is certainly done in bursts, as opposed to being more consistent throughout and is also more fast-paced. The lack of strategy in between sections is a bit noticeable, but I don't think it was too little overall.
Sorry for replying way too late.
Honestly i would have like it more if pikachu finished off the fight after eliminating sandstorm and using thunderbolt on a soaked tyranitar. The part with pikachu deflecting stone edge being used as ash's way to find he can use water to eliminate the sandstorm, with the deflected stones landing on the water. It just feels misplaced, still i like the fight.
Noivern vs weavile was basic, honestly its weird how noirvern used supersonic as echolocation here and the fact that weavile got hit by supersonic twice and didn't get confused was too.
For all the flak tysons battle with ash get, i think the fight against metagross there was better as it actually involve some neat strategy and teamwork to weaken it. It was a great battle, here pikachu gets pummeled and thrown until all he has to do is jump, it just becomes very easy.
No complains about charizard vs pikachu, pikachu selling how exhausted he was, was simple good psychology. I really loved this sequence.
I loved greninja vs charizard, the choreography and animation was absolutely fantastic. I will agree that using water shuriken on the ground to cancel out blast burn was unique and creative, however i cant say the same thing about the water shuriken vs thunderpunch combo as it makes no sense how greninja is able to deflect electric attacks using a water type move, i still enjoyed it because it looked cool as hell. A better choice would have been to use cut. In the same battle, water shuriken is used in a creative way and makes sense, but also in a way that makes no sense. Leon vs lance is similar in a way, as gyarados used aqua tail to eliminate the fire spin field and deflect thunderpunch.
I liked the alain battle, however mostly because of the animation and cinematography. The fighting itself was for the most part basic, the selling and storytelling werent there. I cant rank it above Leon vs Ash or Ash vs Paul for that reason or the sawyer fight either and especially the olympia battle.
