Yeah the replay overall is actually pretty entertaining. I used the fast-tracked banshee play the other night just for kicks, and it worked like a charm heh.
It was sorta noob of Arew to have all his gateways powered by a single pylon though.
Also I've never seen the tech lab swap done before this. Then again, I am super noob
Edit: Tried the tech lab swap tonight. Pretty sweet. It's like instant tanks!
