Hey guys, Solo'd these guys with Pandaren Mechanical Dragonling. Had Emerald Proto-whelp and Spawn of Onyxia as backup, but he pretty much dealt with it all.

Start the round with Decoy to negate the Mana Surge. From there it's just Breath Spam. You can flip into one of the other Dragons if you want to wait for the decoy to come back up, but he solo'd just about all of it.
