Thank you! I've been trying to complete the dex too for the first time but been slacking off. I have all the sources since I own all gen games and almost finish w/ Kanto dex in my US Diamond (I wanna start completing there before transferring to latter gens), but really, shiny hunting gets in the way for me.
Speaking of, I managed to get another shiny from chaining, yay... Its shiny Skiddo after 35 chain & for the first time afterwards I also managed to get to 40 chain! But I didnt reset for another shiny since the chain is reset to 0 after we find a shiny right? At least from what I read.
