After seeing Viola, in both the games and anime, I must say I was rather impressed with her skills for the first gym leader. In the games, it's safe to say that she will give you trouble no matter which starter you pick. Naturally Chespin is at a type disadvantage, Fennekin will have its Fire moves cut short by Water Sport, and Froakie will have a neutral standing.
Then in the anime, utilizing both Sticky Net and Ice Beam as an ice field was pretty clever on her part, while debilitating for her opponent. So I ask you guys, if you could be a gym leader in the games, what strategy would you use? That wouldn't be overly hard, but would be fairly challenging nonetheless?
