One thing I wanna tell you in case you decide to keep Japanese named Pokemon I sent. I was told that Japanese named Pokemon which was obtained from Japanese Pokemon Ranger 3 will be labeled as illegal on legality checker but that's because legality checker didn't get updated with latest Pokemon Ranger 3 meaning all of them are legit.
Last thing, that last shiny Pokemon I traded was complete legit one I caught it myself, just to let you know if you decide to keep it.
Btw, is it okay I add you as friend?
