I'm not a huge fan of the card from my few games with it so far, but I have noticed the inbuilt combo:
Gain Golds early -> Draw cards for big hands to get Govenors and Golds together -> Remodel those Golds into Provinces.
Obviously if you want to be drawing and Remodeling in the same turn, you need quite a few Governor plays, so TR/KC help out here, but I have a feeling this combo was in mind when the cards was designed.
I, personally, would be happy to add Governor to the list of "single card engines" along with the Minion and level 3 Cities, the only 2 other cards that qualify IMO (Although that was before Hinterlands. JoaT probably qualifies now too since it provides the Silver you need to buy stuff).
