I don't think you can delete it, also it is HELPFUL, not HARMFUL. You just need a Wii with Battle Revolution on it. I got a Magmortar =D
You can't. Once you do Mystery Gift, the only way is to delete you game and start over...
get it as a mystery gift from Pokemon ranger
cheat
No there isn't.
Nope, the only thing the Mystery Gift does is allow you to get event Pokemon
you only can get a mystery gift on Pokemon diamond and pearl
When you receive it, go play Pokemon Pearl and go to the pokemart.
No you can't
Get a friend who also has Mystery Gift and do it. I think that's how.
Use an action replay
you dont!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
no, you piece of cow manure
