I suppose there's no way you would trade your pokemo mystery dungeon code for some rare event or rare shiny pokemon in pokemon black or white or black 2 or white 2.
I don't have any club nintendo codes to trade.
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
