Here's why:
* Wonder Cards are a one-time use: They are designed to be used once to get a specific item or encounter a specific Pokémon.
* They are tied to your save data: The Wonder Cards are linked to your specific game save file and can't be transferred to other players.
However, you can still share the benefits of Wonder Cards:
* Trading Pokémon: If a Wonder Card grants you a special Pokémon, you can trade that Pokémon with a friend.
* Trading items: If a Wonder Card gives you a rare item, you can trade that item with a friend.
To share Wonder Card benefits, you'll need to use the following features:
* Wireless Connection: Connect with another player via the DS's wireless connection.
* Trade: Initiate a trade to exchange Pokémon or items.
Remember: You can't directly share Wonder Cards, but you can share the benefits they provide by trading the Pokémon or items you receive from them.
