Okay since I ran out of cool mons to write about in BW UU, I might as well help out here.
I'm looking at
Azelf right now and it seems horribly out of date. The classic lead set is barely seen anymore, CB is by far the most common, and no one uses Scarf Azelf, so that should probably be moved to be an OO mention only.
Flygon can probably use an update as well since afaik no one uses Toxic Stall or Mixed Flygon. Sets should probably be Scarf and CB/physical LO with everything else in AC/OO.
(this is mostly from tournament play experience, not ladder, so I
could be mistaken)
So yeah I'll be working on these soonish.
