I would go Governor/Wharf. Since Wharf takes care of hand size, you can use Governor to gain Golds every time except in the late game where you're remodeling the Golds into Provinces. Always prefer these Power $5s over Golds. I would have totally ignored Young Witch... with your opponent's Nomad Camp in play on Turn 4 he was able to buy 2 protection cards, so your YW didn't slow him down at all. I think even if you got a couple more curses in, it wouldn't have affected things much. If he goes for YW, pick up Oases on $3 and $4 instead of Silvers (gets in the way of Governors while not even protecting you) or Moats (terminal collision).
