I know what you're saying (been there myself ): Doctor and Hermeticist only slow your opponent down, if you don't kill him off in the meantime, he will finally break through... the Mercenaries are a much better alternative!
As Mana says: Counter decks are indeed a real problem with this type of deck. My version also had a gold deficiency, but yesterday I replaced Thieves Guild with Coy Courtesan for more income, and it does help a lot... still not optimal, though.
I suggest you try it and come back with your findings, I'm very curious how you would set it up yourself
