Here's why:
* Shards are a rare drop: Shards are obtained from specific Pokémon by battling and catching them. They are not sold in any shops or traded.
* Shard rarity: Different shards have different drop rates, and some are much rarer than others. This adds to the challenge of collecting them.
How to get shards in Pokémon Emerald:
1. Battle and Catch: The most common way to get shards is by battling and catching Pokémon that are known to drop them. For example:
* Red Shard: Found on Pokémon like Mawile, Aggron, and Aron.
* Yellow Shard: Found on Pokémon like Geodude, Graveler, and Golem.
* Blue Shard: Found on Pokémon like Skarmory, Volbeat, and Illumise.
* Green Shard: Found on Pokémon like Seedot, Nuzleaf, and Shiftry.
* Purple Shard: Found on Pokémon like Nosepass, Magnemite, and Magneton.
2. Trade with other players: You can trade with other players who may have extra shards that you need.
Important note: The exact Pokémon that drop each shard might vary depending on the game version and the specific location where you encounter them. It's helpful to consult a Pokémon Emerald guide or Pokédex for detailed information.
