Nintendo has not sent any gifts over the WFC at this time. Only time will tell if they actually will. Only thing we can do is wait and watch for an announcement.Blah Blah Blah
That option is not being used currently, but will probably be used soon.
It will be a mewtwo in black and white via nintendo wfc from feb 12 to an unknown date
YOU DON'T KNOW IT!?!? It is a thing where you can trade or look at other peoples PC boxes OR... you can look at battle videos well that's what it is in Pokemon DS.
It's only available in Pkmn Platinum, April 20th through May 12th via Nintendo WFC, check www.pokemonplatinum.com for details.
The best way is to connect your game to Nintendo WFC, tap the arrow pointing down at the screen that you go to before you start your game. Tap the mystery gift button and select "Get mystery gift via Nintendo WFC" (That may not be exactly what it says) You have to wait a couple minutes before you get it, but you get a rare or legendary poekmon.
The Gracidea Flower only works during the morning and the day, but it won't work at night.
While still on the title screen you select MYSTERY GIFT -> RECIEVE GIFT -> GET VIA NINTENDO WFC. It will download to your game and you will then be able to pick it up from a delivery man at any Pokemon Center.
So far the only one is the Yellow Forest. You can access it via Mystery Gift "Via Nintendo WFC" until 5/5/10. It is a new route on the pokewalker containing only Pikachu, including rare Pikachu that know either Surf or Fly.
Well, through May 5, 2010 the Pokewalker Route, Yellow Forest will be available via Wi-fi event. To get this, turn on Soul Silver and go on Mystery Gift. Then click "Get Via Nintendo WFC" Then... well it'll tell you the rest. Hope I helped!
You can only get it via Mystery gift. Though if you want, you can trade over Nintendo WFC. At the GTS. Hope this helps! I thought that only people who hacked could get Shaymin, well, unless you trade with someone who has, of course.
The Yellow Forest is a route for the Pokewalker. To obtain it you must be able to access the Nintendo Wifi network via a Wireless Router or a local hotspot (check nintendowifi.com for you nearest hotspot). Then turn on your Soul Silver and from the main menu go down to Mystery Gift. Choose "Via Nintendo WFC". It will search the network and download the gift. Then just go to the nearest Pokemart in the game and talk to the delivery man. He will give you Yellow forest that will show up the next time you connect your pokewalker.
