Updated the OP.
I'll also be putting up Altaria up for reservations again. It was last updated in January and while I've gone and fixed up the Checks and Counters section on my own, the current analysis could use some defluffing. That and the sets could use a change to match with how the metagame is now. (Such as Support set being even worse in this meta, that I don't think it probably deserves a set anymore; Change in EVs for Specs etc)
