First, you get a Gastly and teach it Mean Look and Hypnosis. Then search for Mesprit. You pick mean look as the first move and then switch to a high-level Pokemon that knows False Swipe. Keep using False Swipe until you've gotten it down to 1 health. If you still can't catch it, use Hypnosis and try to catch it again.
Easiest way is to be a Far-Ranged Class :]
beat the elite four, then the girl blocking the way will let you in. just go up from snowpoint city.
anyway get a knife and simple. you know the rest
give me 5 dollarz and i will tell u
Beat the game, Einstein.
shoot alder with a gun
There is no easy way. (see related question)
To find Mesprit, you must have captured/defeated Dialga or Palkia, depending on your version of the game. Once you've done that, go to Lake Verity, surf into the cavern, talk to Mesprit and it'll fly off. If you don't have the marking map from the Poketch company, go receive it from the President in Jubilife, so you'll be able to track down Mesprit easier. If you mean in Platnium version, then it's possibly the same way. Though, that game has yet to come out in America.
in pearl,diamond & platnium,know your pokemons and identify the color change,or look at the pokemon's personal file,and see if there's a mini star.
i suggest, just raise your Pokemon
The easiest way is to catch a Timburr and teach it Rock Smash.
The easiest way to get your first star on your Trainer Card is to beat the Elite four at least once.
