It seems pretty safe and economical right now.
vs Zerg wall the main
vs Protoss position your pylons to defend ramp and mineral line
I've held off 1 base 4 gate Blink attacks, Ravager allins, etc. with this.
Thoughts?
EDIT - worker scout after Cyber is planted to decide if I need to start a Zealot or not.
