The most gosu person on the forum. Who do you think you are? You're like 30% win. As a human player, vs ud and orc i go rifle+sorc. There are a few ways to counter it:
For orc: Docs+taurens with healing wards and stasis wards
Get some wyvs and harass his the mine, then hide in the
trees while he tries to guard his peons. This should
give you time to both tech to doc tauren, as well as
screw his economy over.
For UD: You have to mix army and get overpowered heros. UD is
generally a weak race, but with tri hero (DK lich CL)
+fiends stats necs to aboms, you should be fine. Just
use your heros to jack his heros first, then the rifles
die easy
