well, if he rush blocks you're DEAD. Anyways, a good thing to do against them is to zone, which is "SPAMMING" in a bad players mind. you need to make him come to you, keep him back with skulls, and make sure he doesn't reach you.. OR, you can put a lot of pressure on SZ if you do get up in his face, so you won't have to worry about those clones.
There is another thread about "across the screen" or something, where people were commenting on zoning.
