Where is the best place to train for the elite 4 in soul silver?

Answer 1

I recommend the paths where Pokemon already have higher levels (like down from Blackthorn City), Mt.Silver, Dark Cave (Blackthorn city side), and ofc Victory Road. Best is to train them in places where Pokemon type matters, like water or grass type is easiest to train in caves because rock Pokemon are weak for those types. Fire Pokemon beat grass types easily so grass paths are best for them. Electric-types are easy to train in water, and high-leveled tentacools and tentacruels can be found all over the place.

Best train for Pokemon is Pokemon league itself, as long you make sure you save all your money to your mom / spend it in potions etc. and just go and fight, pokemons grow levels while you win but if you happen to lose, there's no money for you to lose, and happiness points that lowers everytime your Pokemon faints, you can always gain back to your pokemons.
