As You Build Your Base. Have 4-6 Reavers At The Entrance Of Your Base With Some Photon Cannons And A Some Zeleots. Later Cover Em Up With A Arbiter. Reavers Have Great Effect On Mass Ground Units, Mass hydras Will Not Be Able To Get Through Your Entrance. Its Always A Good Idea To Be Building Scrubs As Your Enemy Attacks You and make sure you have all the reaver upgrades done.The Arbiter Can Stasis Field The Hydras To Slow Them Down. For More Secure Defence You Should Have High Templars Ready To Psionic Storm Mass Units And Have Some Scouts Or Carriers To Stop Air That Attacks The reavers.

Most People Think Scouts Are Waste Of Money. Scouts Are Bad If They Are Single But In A Group They Can Stop Almost Any Air Mass Of units.Even Though Their Ground Attack Aint that good, Its Better Then No Ground Weapons At All. With 15 Scouts And A Arbiter *observer(s) Too. You Can Stop The Biggest Mass Of Carriers Or Zerg Air If You Have good Upgrades And If You Tend To Stasis Field Them With Your Arbiter. After You Stasis Field Your Enemy Air Mass, You Can Surround them And attack Each Carrier one At A Time After The Stasis Field Worns Out. For Extra Effect, You Can Have Lots Of High Templars Psionic Storm The Carriers Right After The Stasis Field Worns Out And Bring In Your Scounts Attacking 1 Carrier At A time.

This Defence Strategy Works Great If You Have upgrades Done And You Avoid EMP Shock, Lock Down, Tanks vs Reavers, Plague And Any Other Not Too Common Special Effects
