This strategy is excellent in destroying almost any opponent.


-Due to my laziness, I will not include the beginning (build 7 drones, get a pool, etc). I also don't think it's neccesary.
-After you have a good defense, build massive mutalisks, hatcheries, and upgrade air attacks and carapace. Also be sure to mine a lot of resources, because you'll need them.
-After you have over 50 mutalisks, make 12 guardians, and 12 devourers.
-Make more mutalisks.
-Make 12 more guardians, and 12 more devourers.
-Hotkey all of them, plus 6-8 overlords, so you have 5 groups.
-Send the first 2 groups of guardians and devourers to attack. Also get some overlords in.
-Continue attacking, and if your guardians are dropping fast, get your other group in.
-During this time, continue building more mutalisks, guardians, and devourers.
-Even if you lose many units, you can rebuild very quickly and keep attacking until you have won.
