With Cyclones changing in the latest patch, I wanted to discover a way to still utilize them in TvZ. I (re?)-discovered that with the Mag-Field update, four Cyclones can kill a base very quickly. This build attempts to emulate a standard opening, while getting out four Cyclones and two Medivacs to snipe the main base at around 7 min - followed by a Mech transition.

A few things to remember while executing this build:
This is important! turn off the auto-cast for the cyclone lock-on attack. If this is on, when you drop at their main base, the cyclones will just attack whatever they see first. You want to micro all four cyclones to lock-on to the base. It should be destroyed in approx 5-6 seconds.
Even if the base is protected by queens or some roaches, you should still be able to snipe the base. It's that fast.
My preferred transition is into Mech with a Lib support. I would suggest pumping out Thors sooner than later and keep watching for a Muta switch. Don't be afraid to turtle until maxed (@12-13 min), and then move out, while continue to harass with Libs.
Getting out the viking before the first Medivac is important to deny any scouting.
