Feedback please! If you like the concept, how could it be better balanced? If not, please explain why!

I certainly like the concept and I could see how he could be useful. I do not think that it will decrease the game speed dramatically but it will put more pressure on you to make more of a defensive stand. However I know that some people get annoyed when they are about to destroy the queen but then they win by drilling and this could fuel a lot of tension with certain players but overall very good.
