HMers? Huh... no one's asked that question in the other forum I posted it in. Sure you can have an HM slave or two, but that would just increase the difficulty even further, wouldn't it? My advice is to either make use of a potential HM Pokémon in your final party, or trade said HM Pokémon with someone else for something you would consider to be in your final party. Either way, good luck.
