Your Strategies Are Great And All, But I Am A Zergling Type Of Guy, But I Have One Great Strategy (Espiacially Effective In lsand Wars) That Has Saved Me Resources And Time And Has Won Me Wars. I Morph 36 Mutalisks, Morph 12 Into Guardians, 12 more Into Devourers, And Keep The Rest. Than I Morph 24 Scourges And 4 Overlords To go With Them. The Devourerers Will Draw Attention Away From The Gaurdians As They Attack The Enemy Base From Outside Of The Base Defense Line. The Gaurdians Will Make Quick Work Of Any Ground Defenses, The Make Sure That The Mutalisks And The Devourers  Draw Fire Away From The Guardians, Especially When Faced Against Spash Damage Dealers Like Valkeries, The Scourges Are To Stay Behind A Little Until A Large Problem Like A Battlecruiser enters The Warfare, Have The Guardians Make There Way To Mining Operations And Destroy All Miners And The Primary Building So If You Do Fail, It Wouldn't Be A Complete Waste Of Time, Then Destroy The Base From The Inside. And If It Fails First Time, Try Again, Your Bound To Master It.  (Note: It Won't Be Effective Against Zerg Because Of Dark Swarm, Plague, And Because Zerg Have The Ability To Produce Units Quickly. I Have Watched A Flock Of Scourges Make Quick Work Of My Guardians. And Beware Of Psionic Storm And Maelstrom, They Will Render Your Guardians Helpless)
