Pokemon Team Improvement Thread:
Improve the teams of gym-leaders/important boss fights. Whether to make them harder, give them more fitting Pokemon, or both

I'll start. Here's my improved Johto teams. (note: many of these Pokemon are significantly buffed/reworked to be better/serve different competitive functions. Example: Miltank is now Normal/Fairy, and Whitney is now a Fairy-Type Gym Leader. Dragonair now has a 540 BST, focusing primarily on Speed, Special Defense and Special Attack + now has Drizzle as one of it's abilities, ect. You're allowed to give Pokemon/types buffs, just make sure to mention these buffs)
