haud "astute trading" card and other cards like it

[Squamiger]

After seeing Mitoe send silversmith I tried a similar build using Haud, sending the astute trading card, which increases villager mining and increases the yield of coin mines by 20%. It worked out pretty well for me as a semi-ff: I went 5 vills -> 4 kanya -> astute trading, and just gathered food and gold to age. So, replaced the 800 crate shipment essentially. I find you can make up for not having the wood from this shipment by using the house big button at 10 minutes to get 500 wood. I think it works out especially well in long games where you want to mine as long as possible.

What do you think? What other civs is this card good for now?
