Yes You can get all your pokemons shiny in 2 weeks if you catch all pokemons with Heavy Ball( For Heart Gold) or Ultra Ball!
Heart gold I think so gold no
well there are no common shiny Pokemon in heart gold but i have seen a shiny garados's and a shiny medapod. so maybe garados.
You can't catch Arceus. You can only catch Arceus in Pokemon Platinum.
Literally anywhere you see water. Use a fishing rod to catch one. There all over the place! XD -Chii
You can't catch Arceus in Pokemon heart gold. You must bet it from Pearl, Daimond, or Platinum.
There really isn't an easy way do get shiny Pokemon in Heart Gold and Soul Silver. There is only a 1 in 8192 chance of finding a shiny, so you just need a lot of luck to find one.
just run in the grass
You transfer it from Heart Gold or Soul Silver.
