Pokemon Crystal - Johto Gyms

Compared to gen 1's gyms, there's a lot more strategy to Johto's gyms. Though due to you being given quite good tools for most of them, not the most difficult. Though for example, Whitney can be a roadblock if you don't a Pokemon that can either use Rollout/Fury Cutter effectively or something that helps vs the infamous Stomp/Rollout combo. Shout outs to the Crystal exclusive Teddiursa encounter. Dang its good.
