Yeah, Enslave Mind, Soul Slay and the works will work only on the commander-type. And then... There's a whole plethora of things that work on the Iron Dragons. All the things that work on Lifeless things (like Shatter), all things that work on Magical things (like Opposition, Unraveling). Storm kills their flying ability.

Sure, they rock people's socks off if they haven't had the time to prepare, but they aren't that hot when they are ready. :/
