I think I've found one or two more since last time. I don't remember seeing any extra Anniversary one yet though.

I found 2 anniversary Azelf and 2 regular. I caught a regular but I’m looking for another anniversary one.

Anniversary special? I saw like 6 of them. These azelfs swallowed my ultra ball and few great balls...and I haven't caught any yet..

I found 8 regular Azelf while looking for the anniversary special version. Fortunately I ended up finding and catching one. Just one.
