Maisy may have some decent pokemon allies to help her, but in the end they won’t be enough to take on Ash Ketchum! Ash has many more pokemon at his disposal and they’re pretty powerful. Pikachu could be all Ash needs in this round, but just in case he has a couple dozen more. Maisy drops down the blog ranks with this loss. Ash wins.

We haven’t seen any of Maisy’s Pokemon, other than the Slowpoke that lives with her and Kurt, and the Teddiursa given to her in the manga. In fact, she may be too young to own any (as far as the anime is concerned).
We can pretty much assume that it’s a “no contest”.
Agreed. Maisy just doesn’t stand a chance this time
That definitely puts her at a great disadvantage. Perhaps she will appear in a future episode
