Pokémon Gold and Silver/Blackthorn City

Blackthorn City hasn't got much in it, you can buy ultra balls and Max Repels at the mart and there is a trainer who wants to do a really bad swap with you, a for a female, I'm not saying that Dodrio is a bad Pokémon, but Dragonair is probably one of the best Pokémon in the game and it has one evolution to go. There is also a move deleter, who can make your Pokémon forget HM moves, you may want to do this, but the main thing is getting that final badge. It is recommended that you bring your Red Gyarados (You do have it don't you?) and an Ice Pokémon (something like a Swinub or a Jynx) and go to the Gym.
