Due to the closing of my thread here is Zeratos build order althought I am not sure for what matchup is this ... hope zera can fill us in here .
9 Pylon (Attempt proxy pylon with recon probe) 12 Gateway 14 Assimilator 16 Pylon + Cybernetics (Warpgate)

Push out zealots + Twilight council. Warp in 2 more Gateways and go for Dark Shrine if your proxy was a success. If proxy is still not discovered, pop out more warpgates, expand if you can and go for 2 forges.


From here you can go Archon/Zealot/Stalker if they got detectors (which is highly likely), if not you can go robo.
