This is copied from Dark_Prelate's copy of Beastyqt's build from 2020, but with the e-bay block removed so you don't have to build it if you're practicing. You can do it if you want to, but it's a bit APM taxing for those of us below master league. I think regular mech is now cooler than battlemech since cyclones had their lock on range nerfed from 15 to 9.

The general idea for this build is to harass with battlecruisers and hellions, keeping the BCs alive and sacrificing the hellions to roast drones. After 2-3 minutes of keeping the zerg (and yourself) busy with that, create a composition of thor/hellbat with battlecruisers. Mix in tanks and a couple liberators if you want to perform more than 1 action during your push.
