None u can send and receive all Pokemon.
Yes you can trade Pokemon from Pokemon silver to Pokemon blue. The only restrictions on this is that you can not trade any of the new Pokemon that are introduced in the newer game (Pokemon with the number 151 and up can not be traded to Pokemon blue).
i don't think you can you can only trade from another firered, leafgreen, or a ruby, saphire, or emerald game
The only way is through Link Trade, or Gameshark.
i think the only way is trade from Pokemon red, blue or yellow
Vulpix is only in Pokemon Blue, so you have to trade in order to get one.
Only if you trade it from heartgold with a Pokemon holding it
only if you trade them from red, blue or yellow
It only evolves through trade.
The only way to do that is to trade with other people.
do u mean Pokemon blue or do you mean SAPPHIRE You trade to SAPPHIRE the normal way but u cant trade to blue
No, sorry you can only trade from time and darkness
it's impossible. your can only catch one in Pokemon blue. get a cable cord and trade
