I used legality checker to check if all the Pokemon I traded with you was legit and guess what? All of them passed but I have good news and bad news.
Good news is that shiny Azumarill is perfect meaning it has 31/31/31/31/31/31 IV.
Bad news is, it's not EV'd at all.
Also about your Mismagius, it has pretty good IVs.

And just as you suspected yourself, yeah it's EV'd are little screwed up. It just need minor repair so if you want, I can fix it's EV and give to you unless you prefer original.
