Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
None of those Pokemon are in the No Egg group. It has been confirmed that all No Egg group pokemon (that are catchable in the game right now at least) have three 31 IVs if caught in the wild. http://www.serebii.net/pokedex-xy/egg/noeggs.shtml
Thanks for the list. About to start my next run so might as well do a quick run down of my team the first time through
Azurill: - High
Availability: Flocessy Ranch. Very early on, and not too hard to encounter.
Stats: Attack is the reason you raise Azurill. Its speed is nothing to write home...
