That doesn't matter much. In the first Hoenn episode he couldn't even call out an attack. In less than 50 episodes he fought alongside Ash. Farfetch'd' can achieve a lot at this pace.
I was responding to legendary argument but to your Go's attack argument, that basically happened with other people like some rivals and even companions like May or Dawn who struggled to get first Pokemon but by episode 50 Dawn was fighting in tournament and getting to finale. May IIRC got her first ribbon in episode 50.
I think you misunderstood me. What I meant was Ash has reached a point where he can draw out his Pokemon's power better. I am not saying Ash-Greninja or Charizard is weaker than current team member. It's just that this Ash is better kind of like AG Ash being better than OS Ash. If those old Pokemon return then they would accomplish better feats under this Ash.
I se,e you probably worded it like to seem that every Pokemon he catches in future is automatically stronger than older Pokemon. Of course this Ash is better than AG Ash but Pokemon's power is individual. Yes, older Pokemon are obviously stronger but if they trained. Example if Torkoal from DP never trained for all those years even 30 year old hypothetical Ash if he uses Torkoal, Torkoal wouldn't be stronger than he was in DP since he was lazy, goofing around etc. Yes, 30 yo Ash would probably use that laziness as advantage as strategy unlike DP Ash but power wise Torkoal would be same.
I am not disrespecting any of the old Pokemon. In fact you are disrespecting Ash's current team by saying only Lucario can become an ace. All this boost stuff is fine but a strong Pokemon doesn't need these to be strong, kind of like Flint's Infernape. I think I already answered why his current Pokemon can perform better.
How am I disrespecting? It's already set in stone that Lucario is an ace.You do know that every series has 1 ace except SM and BW which had 2 aces? I don't understand that this is disrespect. Flint's Infernape is an ace, though. It doesn't need boost yes, I mean Ash's Pokemon proved it with Charizard, Pikachu, Snorlax, Sceptile but problem is those Pokemon had time to get there where they are. Charizard OS- BW. Pikachu OS-SM, Sceptile AG-DP, Snorlax OS - BF/DP. Lucario would obviously be in Top 6( like replacing Incineroar) without a boost but for him to be on A-G level or Pikachu by end of PJ he needs Aura boost( like that Aura boost) like that A-G boost.
BTW about disrespecting. I would be disrespecting if I said his current Pokemon would be gym level by end of PJ. No. His current team except Lucario could easily be like between Top 7-8 to Top 15-16 by end of PJ saga( like on level of some Frontier Brains). Dragonite probably be second strongest in current team. Sirfetch'd would be third. My point is that make no sense that even by end of PJ that his current team( except Pikachu and Lucario) comes in Top 6 like above A-G, Charizard, Sceptile, Incineroar, Infernape and they're not aces , they had less time in training and they don't have BS power ups.
In Cynthia vs Aaron match, her Gastrodon took out two of Aaron's Pokemon. If Ash is looking forward to beat Leon then his whole team should also be able to match Leon's team which is most likely stronger than Cynthia's team. Calling old Pokemon is fine but his current team can't be fooling around while he calls old mons back for battle. I don't think he will call reserves though.
That's my point, Gastrodon is not ace( like Aegislash) and he/she took out 2 non aces of probably weakest Sinnoh E4. Point is that E4 non aces( like Champion's) are not weak. That's why Aegislash is wild card: it could be nerfed it could have soft spot like Shadow said that it would go down no matter how powerful it is( in Blade form), it could hold back, it could be his weaker mon outside his party. His team to match Leon's team is why Ash has to call reserves: Charizard, Greninja to return, Sceptile, Infernape, maybe Snorlax. But also don't forget that Leon vs Ash will probably be 1 on 1: Charizard vs Pikachu.
