Pokemon Bank is basically a cloud storage system. We pay $5 a year (presumably; it hasn't been confirmed outside of Japan yet) to use it, and it is necessary to transfer Pokemon from gen 5 to gen 6.
Is it the only way? I was hoping to be able to use my old DS with Black/White to trade my old Pokemon to my 3DS with X/Y... Or wait... can we not trade Pokemon that we have received through a trade? I kind of traded some really important Pokemon to myself between Black and White already... Well, if I can't trade those, then I guess $5 a year is a good price, assuming there's no long-term commitment and you can get all your Pokemon out of there before the next year. --- ACNL QR Codes: http://pikangie.tumblr.com/ 3DS Friendcode: 4597-0805-4383
