"As you may or may not know, currently the only way to acquire certain Legendary Pokemon in the Diamond and Pearl titles is to attend very limited specific events.

However, these Pokemon already exist in the game and are unlockable via Key Items. We humbly petition that Nintendo distribute these items of the games through the WiFi Mystery Gift feature, thus allowing everyone around the world to acquire them.

The item in specific we are requesting, is the Member's card which would allow us to partake of the Darkrai event. We would hope this petition allows Nintendo to know that there are people who want to obtain Darkrai in the game without cheating."

Here is an example of item's existence in the game: http://img.photobucket.com/albums/v185/Transfan2/d9fd_3.jpg
