Jangmo-o location? (any other newly added pseudos as well)

[JIMMY!!!]

So, I wanted to know if there was a way to get Alolan Jangmo-o because they introduced its aevian form that you can get and other pokemon like aevian magikarp as well as its original form.

I also would love to know if there any new pseudos like dratini or bagon if anyone has info on that
