Set aside a Gaining Village from the Supply. During cleanup this turn, discard it.
The bottom part really just means "gain a Gaining Village", but is so worded so that you cannot piledrive Gaining Villages with Watchtower/Extreme Trashing.
So it's similar to Port, difference being how you get the village. In general Gaining Village has the potential to get more other GVs, but Port gets you one earlier, ensuring you will get the free Village before it runs out. Hence I think they should be the same cost.
What do you think, especially about how it compares with Port?
