Soooo.
I was planning to preorder Pokemon Omega Ruby, and then save up some money to buy a 3ds XL. One of the reasons I wanted to preorder the game is that you can download a shiny Metagross for a few days after the release. Since I won't actually own a 3ds for quite a while after the game is released, I was wondering if it's possible to download it using a friend's 3ds... Like, could I use an SD card to download it, then use that SD card once I obtain a 3ds, or is that even possible? I just want to figure this this out so I don't have to preorder it for no reason. Thank you for any help.
