Start out by makeing your scvs then at 8-9 make a supply depot. Keep making scv's and another supply depot, then with that same scv make another command center in the mineral patch next to you. Get another scv and make another supply depot (while continuing to make scvs) now send it to make another command center in another mineral patch.

Once your first command center is done, start pumping out scvs only up all of them on gas (3 on each guyser, 4 guysers). Now out of your other command center start making scvs and puting them on minerals, only take every other one untill you have 6 builders.

Make a barracks and have the other builders making supply depots. After the barracks, make a factory, and an academy, continueing to make supply depots. Build 2 armories, and upgrade air. now begin makeing starports(only put contorl towers on 3 of them) till you have 12. At this time you should have about 60 scvs mining and getting gas on atleast 6 guysers. Now get your 6 builders making a science facility and supply depots till you have 200. while doing this, start pumping wraiths out 12 at a time. Once youve maxed out at 200, scan your enemys coast line for air d. Whatever side has less d is the side you attack. Fly right past the d, hitting minerals. Kill the workers and then the town centers one at a time. If they send a lot of ground troops, simply run to the other side of the map. If they have a lot of air massed, send your cloaked wraiths to the middle of it, killing it before they can use it.

You should be maxed out and have lvl 2 air upgrades at 13 minutes, and most shared maps are "no rush 20". While attacking, keep upgrading and making more wraiths as they die, only dont send these ones to raid, keep them for the counter attack.I have never lost on shared using this strategy.

CreepColony's Opinion: This is a good strategy, but if your opponent has mass hydras, you're fudged.
