Great batrep!
I'm still in the process of trying to pick an army to play. I own nearly all of the army books and have been slowly play testing different armies. However, every time I look at the Lizardmen stats and costs I am always left with a "How is this even going to work?" thought process in my head. Well in this batrep you showed me how it could work.
Also, the Cold One Calvary.. They did seem to be quite lack luster. Are they better if you use them to flank charge for your anvils?
Again, good job!
