Well since I don't own a japanese game I have no way to get DW bulba or torchic, about the others two, if you don't care about IV's and natures I can trade right now. If you want at least good IV's I need time to RNG them (and the details like: gender, egg moves, IV's, nature, etc)
(about the DW starters, if you want to use then in official real life competitions held by nintendo is better to avoid then since the 90% of the ones's offered, on any site, are pokesaved or hacked. The only way to get 100% legal DW starters is to ask a RESPETABLE member of the trade community, like the mods on pokecheck)
