This build order is inspired by forGG's HotS TvT mech opener. A quick reaper is built for scouting, followed by hellions for defense and cloaked banshees for harrassment. If you believe your opponent is building banshees, skip the two banshees normally built and get a raven and viking. Vikings are built after two banshees for anti-air, as your ground army consists solely of hellions. Hit your opponent with your hellions, vikings (land them if there's no air), and any surviving banshees as soon as blue flame finishes.
If this timing attack doesn't kill your opponent, add on 3 more factories while grabbing more bases + upgrades and play the rest of the game out as a standard mech TvT.
