start mining and get two pylons. when they come on get 4 more workers and an assimilator or two and get gas. get 3 gateways and 3 forges.get 2 more pylons,7 workers, 2 gateways, and a cybernetics core. build the tech tree up to the templars archives and get all technologies there and upgrades at forges.start getting mass dark templars and high templars. get as many archons and dark archons as you need and build cannons all around your base for defence. send out dark templars first to test their defence, then high templars to back them up when they come in to "save themselves", then send in archons and dark archons. use mind control as much as you can (try to get units other then your race) and get some of their workers too so you can get extra population. if there is another enemy get a robotics facility and make 2 shuttles and then get 2 starports and fleet beacon so u can get web. now fill 1 shuttle with dark templars 1 shuttle with high templars and send them in on the side -AFTER- you use web on the side of opponents base just incase and drop in mineral feild. send in archons and dark archons in front and use some maelstorm on big groups infront. use storm on the workers and let dt's wreak havoc.

CreepColony's Opinion: I don't recommend using psi storm with dark templars and archons, since they are melee units and storming will probably hurt yourself. Also this strategy is very risky against terran, as EMP Shockwave will render your archons virtually useless.
