Merchant Confederation (22+1=23), besides the obvious Serfdom, and the occasional Gothic Architecture and Professional Army/Reutines, i think this one is a card I consider before of after in my games, if I need to push my gold output. It also improves quite a bit when the game progresses and more envoys are available, so let's upvote it now we have still worse options.
On the other hand
Town Charters (3-3=0): Eliminated. It has been a difficult decision whether to eliminate Town Charters or push down Medina Quarter, but I'm going with Town Charters as I think the reasons exposed to keep this card vs the reasons exposed to downvote it are more solid than for Medina Quarter. Town Charters is there to provide gold, but as states, doubling adjacency of CH is not that much. Triangles may help, but if you are building docks you may get equal or better benefits from Naval Infraestructure without needing the CH. Also, see Merchant Confederation above. And gold-saver cards as Professional Army may provide a higher net benefit. On the other hand, I'm not a fan of Housing Cards, and Medina Quarter may even be outshined by Civil Prestige, given you not commit your governors to a specific city or spread to much. But I'm not that sold in the argument three districts is a big prerequisite... as probably is in cities where you have already built three districts were you need that extra push to overcome the housing limit. Something that always happens? No, but I still see it more useful than Town Charters.
