This is a very versatile build that is easy to execute at a low skill level but also allows for alot of extra stuff to be done if you have the skill to do it. To sum this build up it combines the power of a 11-12 min push like a 7 gate immortal all-in with the ability to safely take a third at the same time and to have fast HTs along with stargate and robo units. Below I will out line the build in stages and then provide a condensed BO at the bottom.
1. Your first few voidrays can be used to gain map control and hunt overlords. However, you will be showing your hand and letting the zerg know that you are going stargate I like to try and hide them hoping the zerg will try some roach base play which with voids is easy to beat.
2.After your initial push you can do some fun warp prism harass pulling the zerg army all over the place. This type of harass will help keep lings or mutas on the zergs side of the map since the zerg will need fast units to defend against this. Also you will be able to do storm drops almost immediately after the push since you will have storm very early.
3. Zealot run byes will be very viable since after the push most of the units you will be building will be gas heavy and be being slowly from your robo or stargate this along with your three bases should leave you with left mineral that can be spent on zealot to be suicided into zerg expansions.4.Voidrays our also great later in the game since they can fly around and quickly pick off overlords and key tech structures.
You need to scout out after the first pylon because you need to know if your first cannon should go in your mineral line or at your wall.Your scouting probe should check for a natural and a third a little after 3 min. The reason being if the zerg hasn't taken a third and is doing a 2 base play you won't be pushing but instead getting up your third and preparing some defense. Secondly and most important is if the zerg has not taken a 2nd then you need to prepare for a baneling bust or some nydus play. If you see no 2nd you will need to cut voidray production and start getting out sentries, more cannons at your wall, more gateways, and a few stalkers to patrol around looking for overlords so no nydus pops up in your base.
.After your push or after your third is up continue to scout with some observers if you see the zerg going hydra roach its a good time to push since voidray, zealot, HT will be easily able to crush through this plus you will probably be hitting the zerg before they have infestor or vipers to support their roach hydra.
.If after your push you conclude the zerg is going mass muta play d-emphasize voidray and colossus/carrier production and focus on purely stalker and HT. DO NOT make mass pheonixes they will not be as useful in the late game and will require more micro to be effective than stalker and HTs. Instead build up a decent number of stalkers with a few HT supports and make voidrays as you can remember your in defense mode for a little bit. After you have enough stalker to split between your based and and few HTs at each base you can go back to voidray and colossus/carrier production. Doing this will completely shut down mass muta since they won't be able to harass and their corrupter's will be shut down by your voidrays. Furthermore while your shutting down their mutas your warp prisms and voidrays can be harrassing and weaking their base for when you do push and when you do push you will have voidray, stalker, HT, and possibly some carriers or tempest which will make for any easy win. and if it goes into a base race well you will have cannons and some HTs at home killing off mutas while you rock through their base.
If after your push you conclude that the zerg is going for swarm host play then harassment will be important to slow down the end game goal of the zerg to establish a spine/spore wall in the middle of the map with swarm host. Harrassing with your warp prism will pull the swarmhost back and forth and force spines and spores early than the zerg wants to make them. In the mean time build up your void rays to around 10-12 you don't want pure voidray. Then get out carries or colossus your choice i like carriers because it i can move around their defend postion and locust cant attack them. Then add in some HT for storms on the locust and swarmhost along with zealots to by the HTs enough time to storm and lastly 4 tempest to snipe key units and force engagements. You probally will be able to push before their position becomes to strong and if the position does get to strong fly arond leave cannons,zealots,and Hts at home which will hold off swarm host push for quite awhile while your voidrays,carriers,tempest fly around and destroy their infrastructure.
Corrupter/ Infestor/ viper/ with ling or muta:
This is the only build that the zerg can use effectively against this but can still be easily beaten. The first thing is if the zerg goes for a third and then into muta play you should be able to end the game with the push since the zerg won't be able to mass enough mutas to kill your stalkers and voidrays and the zerg will be overwhelmed. If the zerg goes for 2 base real fast mutas stay back defend the get up your stalkers and and HTs with voidrays when you can. Then try and push if you see an opportunity before to many infestor come out. If you can't, defend, work on upgrades, Harass, and slowly expand their are only 2 things right now that can beat you being harassed to death and a bad engagement out in the middle of the map were your army is fungalled to death. Your army is slower so you don't want to base race so before you move out make sure you have good cannon coverage, sentries at the wall at your natural to FF ling run byes, HTs at each mineral line, and use gateways at expansion to form wall offs and chokes. When you do decide to push make sure your army consist of voidray (10-12), a decent amount of stalkers, HTs (4), and then some tempest and carriers how ever many you can afford. The tempest will allow you to snipe vipers and infestors, the voidrays will deal with the corrupters, the stalkers will help to kill of infestors and help out with the corrupters also, the HTs will help to keep mutas and lings out of the fingt, and the carriers will force the zerg to focus fire units to avoid wasting shots on the intercepters and will provide a surprising amount of aoe damage.
