You cant they all are banned from Wi FI there may be a cheat code for i though like for Action Replay but not sure.
if you have Pokemon pearl or diamond you can connect 'em up and send legendarys from your ds to Pokemon battle revolution. :)
Just put them in your party like other Pokemon. There is no specific way to use them. You just make them battle like your other Pokemon.
Yes, but you obviously need Wi-Fi connection. The Pokemon company also put a blocker on it so your Pokemon have to be totally legit (this means obtained by non cheats)
If both of your Pokemon are legendary Pokemon you shouldn't take one of them out or else you cant put them back in. For instance if you are Giritina you cant put in another legendary in your team but you can put regular Pokemon in.
I put a link to a guide all about legendary pokemon in HeartGold in the related links.
They will simply gain Exp. You can't breed legendary pokemon.
Yes, you can through trading with wifi.
put it on wifi, lol. you want a shiny Pokemon, or you want a shaymin, lol? because everyone on wifi wants one:L put it on wifi, lol. you want a shiny Pokemon, or you want a shaymin, lol? because everyone on wifi wants one:L is the shaymin shiny because if it is i will trade a different shiny Pokemon for it
Put ditto in daycare then, put the Pokemon the should be breeded (Cannot be a legendary Pokemon or ditto)
Easier than you think.First,go to copy pokemon,then turn on your DS,go to the menu,and there will be a option that says,"connect to wii"then put arceus in one of your battle passes and you'll be able to battle with it.
you have to go onto the home page thing that says start game/ new game/ wifi. you go in to wifi and put in your wifi code.
you can not use the pokemons unless you have wifi you can put in offer a realy good Pokemon like lucario or a regi and some one is going to trade the Pokemon you want for the one you put in offer and woala .but you can not have the pokemons from the pokedex.
