Fundead! Why, because you make all kinds of crazy units and some of them are just designed to piss people off in rushes. Fiends screw up air, Necromancers screw up with thier mad summons (if they can get a lot going), and Banshees for that possessing fun just to turn thier units against them (once possessed 3 doctors and 2 tauren, was called a noob for it)!
