Lol indeed. Lt. Surge is simply great in both the anime and the games along with the manga adaptation as well imo, and Pikachu vs Raichu was amazing hands down haha. That episode's gotta be my personal favorite nowadays without a doubt.
I was going to get Leavanny, but it's a primary bug-type, so I didn't want to go borderline. I'm being traditional here, so I'd rather use Erika's Pokemon rather than choose any grass-type. Meganium would be another choice
