Pokémon HeartGold - Gym Leader Gauntlet

I took on all 16 Kanto and Johto Gym Leaders with their post game improved Gen IV teams, all in a row! With no healing or revival items.

In HeartGold and SoulSilver it's possible to schedule rematches with all 16 of the Gym Leaders. And possible to have them all gather in the same place, at the same time. Watch the video intro to see how I set this up.
