In a no-rush game, do the usual mineral/gas collection stuff, and build your Gateway, Cyb. Core, and then a Starport or two (in a $$$ game, three or four would be preferable, but any more would take up a lot of space). Build a Beacon but NOT for carriers. At this time you should have in the Cyb. researched aerial weapons to at least level one. Research upgrades for the Scout and then GO CRAZY WITH THEM. Against Terran, I have decimated expansion bases in about a minute with one group of scouts. You do not have to research plating unless abs. neccessary (Shields would be a plus, though). Works best against Terran and Comp. One should not rely on any one unit too heavily, so some Dark Templars would greatly add in your efforts. BEWARE OF MASS HYDRALISKS!!! They will do more damage than you'd think! Remember to leave a few Scouts at home!!!

CreepColony's Opinion: Scouts are pretty expensive, so I suggest you only use this on a money map.
