Initially, your Trainer Card, if you look at it, will be colored blue. There is a way to change that! By meeting certain conditions within the game itself, the color will change: it first goes to bronze , then silver , then gold .
There are three conditions to initiate any change, and these can be done in any order (more or less).
- Defeat the Elite Four and the Pokémon League Champion.
- Earn a 50-win streak in the Battle Maison, including the boss marking the 50th win. It doesn't matter the battle type.
- Complete the Hoenn Pokédex in full by capturing one of all Pokémon within it. Jirachi - an Event-only Pokémon - doesn't count towards this, but all 210 others will we believe.
