Instructions
Find every Pokemon in the world of "Pokemon SoulSilver" to earn a star for your Trainer Card. You will need to locate all 484 Pokemon to finish the Pokedex. This excludes monsters that are only obtainable through Nintendo distribution events, such as Deoxys, Jirachi and Mamaphy.
Finish a 100 battle winning streak in the Battle Tower area. Battle Tower is located due north of the Battle Frontier. Battle Tower pits the players' three chosen level 50 Pokemon against 100 teams of Pokemon trainers and their trios of monsters.
Walk through grassy areas and talk to your Pokemon to randomly find Shiny Leaves. The spots where you can find a Shiny Leaf depend on the nature of your Pokemon. For example, a Bold-natured Pokemon is more likely to find a Shiny Leaf on Route 24. Locate five Shiny Leaves and talk to Lyra or Ethan in New Bark Town and they will add a star to your Trainer Card.
Beat the eight Pokemon Gym Leaders and the Elite Four to earn a star for your Trainer Card.
