>>53029306>HA mons, ArceusCan be injected with PKHeX, though in my opinion, you're honestly better off using Gen 5 Save Tool for that, since it actually gives you the ability to inject Dream World Pokemon with their proper moves and other things, to be as legit as possible. This also includes the game you're injecting to, for better or worse.
>cultivate berriesLiterally just inject them at this point.
I'll admit that I wish someone would recreate the Dream World, but it doesn't seem too likely at this point.
