I know things have been disappointing so far, lack of reserves was the biggest by far and then the opening match was a bit of a joke. But all that aside, I'm looking forward to the upcoming battles! There's always potential for the writers to screw this up haha but let's take a seat, relax, and try to enjoy what's in store for us.
Lance vs Diantha is a low-stakes battle so they're unlikely to job anyone and we might see a close, see-saw battle against two Champions, both of whom have something to prove. Also I'm really glad Lance's Dragonite is his Ace here, Red Gyarados is cool and all but Dragonite is the iconic one.
Cynthia vs Iris features most people's favourite Champion against a previous protagonist and also has some history to it, and from the trailer it seems like this will be a very even fight. Might even be the fight I look forward to the most in the Group stages seeing as it isn't completely set in stone that Cynthia wins as opposed to Ash vs Steven.
Ash vs Steven is an Ash battle so it will probably have the most effort put into it, nothing much to say honestly but it will be incredibly satisfying to see Ash beat one of the stronger Champions. I expect Gengar to play a big role here, it already has experience from beating Paul's Metagross and has Ghost type attacks + G-max Will-o-wisp for a strong fire attack too. We already know that Pikachu battles it too so either Pikachu getting defeated earlier or Gengar getting defeated and then Pikachu finishing the job will hopefully give respect to Metagross.
Leon vs Diantha/Lance is probably the least exciting upcoming battle as it's already decided who wins and there's always the chance the winner gets the Alain treatment. But I'm hopeful that they'll give respect to a fellow game Champion and actually make Leon look vulnerable, so that Ash beating him looks even slightly realistic. There's a lot they can do right or wrong with this one, let's see.
Ash vs Cynthia, I think we've all been waiting for this one for 10+ years! Ash battle aside, there's also history to this one plus Cynthia is one of the most beloved Champions and her Garchomp is one of the most iconic pokemon that we've never seen beaten before, all starting from when it made Paul look like a chump. I'm keenly looking forward to this one and I just hope they give the appropriate respect to Garchomp, it's one of my favourite pokemon and has been shown to take hits like a Champ so hopefully no Lucario one-shot shenanigans here (since Mega Lucario is most likely to take it out). On the off chance that this is Ash vs Iris though, it will still be pretty exciting and Iris will already have proven herself considering she beat Cynthia. That will be a great match too but honestly, most signs point to Cynthia atm. Let's see.
And lastly, the final! And honestly, there'll be nothing more satisfying than seeing that overpowered Charizard going down! Hopefully a Pikachu Z-move to the face to finish it
And since this is very likely a 6v6, perhaps the only 6v6 at all, and they'll probably give this one a good number of episodes and put their best effort into this, I think we'll have a cracker! Ash vs the strongest trainer in the world and he has a chance to win! Our boy's come a long way :')
