I've always really liked Mr. Graves. He hits just as hard as the models already mentioned and is just as survivable. He also has black blood. This can make your opponent think twice about how they want to handle him. But, his best use in my opinion is his show you the door action. Who doesn't like a 6" push on a key model followed up by him pushing into base contact with that model?
But, honestly, all of these models that we're talking about can do a lot of work for you.
