This tactic is about 2 things: power and deception. Ok, first set up a fake base with LOTS of stargates, a few fleet beacons, and an arbiter tribunal. Then announce: "I am NOT gonna go carriers, so DON'T get defences for the MASS CARRIER ASSULT that I'm NOT preparing!" Naturally, they'll expect a newbie carrier raid. Back at your main base, get a bunch of fully upgraded reavers. Pack them up into shuttles, and build some arbiters. (Note: this tactic doesn't work the best against Zerg) Send your little group of arbiters and packed shuttles strait for the enemy base. The enemy will think: Aha! What a newbie! I'm so gonna kick his a- wait! Where the heck did all those reavers come from? Hey, that's cheating! You, uh, you got map hack!!! Now your opponant is suffering from mass amounts of scarabs. Plus, they have to get rid of the arbiters before even thinking about the reavers. (Note: Before hand, do a REALLY weak anti-detector strike. This will convince your opponant that you are a newbie, and get rid of detectors.

CreepColony's Opinion: I would waste money and time making all those stargates.
