When you think of a difficult Pokémon Gym, what comes to mind?

For me it’s Goldenrod City Gym in Johto, Whitney’s Miltank.

Pokémon Gold was my first ever Pokémon game, and Miltank would wipe the floor with my team.

Even now, when I’ve gone back and played it again, the combination of Rollout and Milk Drink is just incredibly OP.
