I think Uxie/Magnezone is basically a tossup. Magnezone's steel-killing ability is significant, but with fully four Outragers, there's probably already a problem if you're not overloading Steels to the point that they fall. Uxie's better speed and greater bulk in combination with Memento is pretty tempting to me, although you're not going to go wrong by replacing it if you do.
Also, we've finally got someone in this thread who knows when it is acceptable to include a Scarf! Given that the team is focused on spamming Dragon, have you considered using Latias instead for more power? Or do you find yourself using Flygon enough midgame that the Pursuit weakness Latias carries would be a hindrance?
