I found this exploit, and I haven't seen it anywhere in the comments, so I'll post it here:
As you may know, the z hotkey allows you to quickly build more of the previous unit you selected in the build bar. What you may not know is that this works with ZAC Assimilators, and it ignores the 3 Assimilator limit. Remember to keep some Nyon Exists for the shielded enemies!
