Yep. Wallace cup says hi.
To be fair, May decided to use what was frankly her newest team member who had just evolved and May had little experience with where as Dawn used her most experienced one in Piplup...and even then it was by a silver that Dawn pulled it off.
I will say that Dawn did have a better time than May did when it came to contests (sure she lost a few, but she did make it into the finals of her first grand festival), because she knew that's what she wanted to do from the get go and her mother was a top coordinator that she was able to learn from, but at the same time could battle in her own way and knew how to perform in contests, here as May didn't know what she wanted to do at first, and got influenced by Ash's combat style which wasn't fit for contests.
I do suppose though if we got an episode showing off contests, it'd be nice to see Serena or Dawn for it, maybe both, cause even if it's something Chloe wouldn't do (since we don't know what she will do if anything), showing off all aspects of the pokemon world is still a cool thing to do in this series.
also depending on on how long Iris stays a request I would have is a Gary vs Iris battle; it’s so random but it’s the battle we never thought we needed.
you know something i'd like to see, Gary interact with Goh and perhaps be the one to ask him what he intends to Mew if he were to capture it.
Because simply owning one of the two progenitors is not a good enough answer to me, plus he might give Goh some research tips and make him take the concept of capturing pokemon abit more serious.
