Okay so let's break this down. I don't understand why people think Paul's new team is weak. Paul is using:
Ninjask
Why do people think this guy is going to suck? If memory serves, Brandon of the Battle Frontier has one. So they are definately not weak in the anime. Let's not forget that it has an awesome ability and can also baton pass boosts to the powerhouses in this team? It probably isn't there to get wins, just for strategy. Probably.
Gastrodon
So it's great that East sea is being shown for a start. But anyway, Cynthia has one of these which again shows that they can be strong Pokémon. Not only that, but it's a great type combination that Ash's team will probably struggle with (Apart from Torterra obviously).
Froslass
I actually missed the episode this was shown in so I don't know what they're like in the league. But I do find it peculiar that Paul has a Frosslass, doesn't seem to fit him. However a Glalie does seem like something Paul would use (Something Ash has).
Drapion
Aaron of the Elite 4 has one, and from the screenshots it looks like it's giving Ash a hard time. So in no way is this weak.
Aggron
Consistently shown to be strong throughout the Anime, not only that but Steven Stone also has one. So, this one isn't going to be that weak either, especially under Paul. More than likely it's been through Hoenn as well, due to it being used as a Lairon against Brandon (Assuming it's the same one).
Electivire
Throughout the entire saga I don't think it has lost a battle. Need I say more?
So yeah, this team definately won't be weak. Oh and it is Paul who is using them, there is no way they are making this easier for Ash. This is the same character who releases Pokemon if they aren't up to standard and is also the same character who's been through other regions. He knows what he's doing.
On another note. Gliscor.
I'm not sure, it's great that it's coming back. But I would have really loved to see one of Ash's reserves come in and show Paul just what kind of power he possesses. But whatever. Gliscor will probably have mastered battling in the air by now thanks to his training (It's also worth mentioning that time isn't measured in episodes, but in actual, you know, time. We don't know how long has passed since then, the writers don't want to show boring walks through a field for 20 minutes do they?). So Gliscor should prove a much more agile threat to Paul now.
And as much as I hate predictions of the battle, I'm gonna go give it a go.

If my prediction is correct, then Torterra is really unlucky.
And I think that's the longest post I have EVER posted.
