Well, now Cybrans are OP as hell, Medusas will paralize your army, Corsairs would blow up your ACU ass and if that doesnt work, add some fire beetles, T3 stage? some loya rush, enemy handle it? early monkeylord, brick spam, telemazer, megalith etc...
The thing is that cybran was always OP save beetle which got changed a bit. Medusa was actually nerfed from Isen's time iirc.
It's just that no one really noticed
