no. You cant. Best shot is Pokemon Shiny Gold which is different but same at the same time.
You select "Move Pokemon" on the little computer in a pokecenter.
You can get it in Pokemon Black and White if you send a special Celebi from Pokemon Heartgold, Soulsilver, Pokemon Platinum, etc.
you choose the Pokemon you are going to send from ranger and click send you then at the same time heartgold has to be on mystery gift searching for gifts from firiends
You cannot. Once in Black/White it cannot be sent back
Nope, there is no way to trade or transfer Pokémon from Pokémon Gold over to Pokémon HeartGold. The DS games are not compatible with the original Gameboy and Gameboy Color games.
Buy mail then attach it to your Pokemon write whatever then trade that Pokemon to a friend they can read it then send it to there PC.
30.
You have to get it on Pokemon diamond/ pearl then send it over (or use an action replay)
You can't catch a Wailmer in HeartGold but you can trade with someone to get it. Or you can do what I did and migrate it from another game. But be careful, if you migrate a Pokemon from another game you can't send it back to where it came from.
to send air mail(or any other type of mail in any game) you have to give the mail to a Pokemon and trade the Pokemon to somebody else so they get to read it.
There is no best Pokemon on Pokemon HeartGold.
There isn't a date for the Arceus Event in Pokemon HeartGold (unless you mean the event where you get Arceus). When you send over any Arceus into your HeartGold game, the event is activated. You'll have to go to the Ruins of Alph in order to do the event.
