Unit Stack:
-Eight Dark Templars
-Four High Templars
-Three Archons
-Six or more Corsairs
-Two Observers
-Six to Eight Shuttles (optional)
Alright. This is best done on a mondo money map since it's hard on gas. Also, this is the absoloute minimum number of units, but make sure to have even numbers of Dark and High Templar- IE, you can have 4, 6, or 8 High Templar, but not 3, 5, 7, or 9. also, alwase have twice as many Dark Templar as you have High Templar. This is Protoss Vs. Zerg only! It helps a LOT to hve Disruption Web, and it is also useful to have Plasma Shields at level two or three, since this deals with Archons. Also, don't even think of trying this on the main base. If your still reading this, your ready to do the SHIFTING ATTACK! Alright, first use your Observers to see if he has a buncha burrowed Zerg in front of his outer defense. If so, do not execute this attack. If, however, he does not, it's time for the SHIFTING ATTACK! First attack his Sunken Colonies with your Dark Templar. Obviously, he will send out Overlords. When they Detect you and you are attacked, pull back the DTs, and nail his Overlords with Corsairs. They will retreat, and almost certainly counter with Hydralisks. This is okay. Use your Shuttles to pull out the DTs, and pull Corsairs out with them. Use the Corsairs to defend against Scourge. Re-land with the shuttles and Re-KILL. Only this time, Don't pull out. Come in with High Templar that have Psionic Storm and preferably Khaydarin Amulet. With Khaydarin Amulet and four templars, you have TWELVE PSIONIC STORMS!When your done psi storming the crap out of him, fuse your High Templars, and use the DTs to buy time. When they are done, come in with your five Archons and KILL. Now you have time to fuse half of your Dark Templar into two Dark Archons. If you have not already, you could Mind Control a Drone since you pretty much just wrecked his base, or you could use them for Maelstrom. Now just bring in Dragoons or something for cleanup. This is called the SHIFTING ATTACK because you shift over from Templars to Archons. Have fun!

CreepColony's Opinion: Requires some micromanagement, and most people who play big money maps don't micro at all.
