This is the March 2019 entry of Metagame Build Orders.
TY recently has been using a TvZ build that resembles the characteristics of early three Command Centre and 2-1-1. I first saw this in his game against Rogue in Olimoleague more than a month ago. The build is unorthodox but well thought out.
Mech is evolving after patch 4.7.1 kicked in. I want to discuss some of the interesting innovations with the current mech style.
