06-29-2025

🌊 Misty’s Water Squad Takes on the OU Ladder

Continuing our AI-powered Kanto Gym Leader Challenge, we tasked Poké Team Builder to assemble a Gen 9 OU team inspired by Misty’s iconic Water-type Pokémon. Could AI strategy help Misty’s waters rise above tough competition?

Here’s what happened.

🌧️ Team Overview

Misty’s AI-built team revolved around leveraging rain to boost its offensive pressure and defensive longevity. This approach led to solid performance, winning 6 out of 10 battles on Pokémon Showdown. Aggressive Rain-boosted attackers like Barraskewda and Azumarill dominated, though dedicated Grass- and Electric-type Pokémon presented clear challenges.
