It looks preety good nice to see lots of skinks! However I think you should consider dropping one unit of kroxigors and beffing up the Oldblood a bit more or maybe adding a couple salamanders. Also you might want to increse the skink unit sizes to 13 so that they can take 1 more causlyty before losing 25% of the unit. Also think about the cube of darkness and mark of the old ones combo. with it you almost have a definite chance of shutting down your opponents magic phase.
