I think that's an accurate assessment, I'm drawing into Earthquake so Free Speech is really your only out and I think it delays the inevitable more than actually turns the game around.
I don't think you played particularly poorly, though I think Hounds are probably a good choice at tech 1 against this deck: unless Arg is already down and able to use his midband, it lacks cheap targeting for tech 1 units (Stewardess obviously makes quick work of skeletons).
I'm not sure what you planned to do with that Vir peek, though. You wouldn't have gold for the Void Star or Hive. I think your best bet was to get Omegacrons down on turn 4, and survive base killing long enough to get them activated. You combo them with a Free Speech, and you can ace Rook with just one of them. Building the tech 2 on turn 3 though is risky board position conceding against Rook, as is bringing heroes out and not being aggressive with them.
I'm happy to switch sides and take P2, or play another deck, or stop playing all together, whatever you'd like
