Mamluks were a house and allowed me to play extremely fast and loose with actions that would have sacrificed the units otherwise... which is good, means the enemy didn’t really have time to reinforce. Blitz on them was just disgustingly good, imagine being able to attack twice and still getting three or more movement points to get to the backlines. Like I said in the original post, they were able to stand toe to toe with winged hussars. I haven’t played too many games with 4UC yet so can’t say how well they stack against all the other new units, but compared to the three I did (celts, zulu, and ethiopia) Mamluks were far more impactful, something I didn’t really expect from a civ that isn’t really kitted for domination. The UB was interesting but the resource generation didn’t synergize too well with my game since I had 0 other plantation luxuries (or bananas) in my core cities... they also messed with farm triangles and the extra bonuses over the watermill were mostly forgettable. I’d imagine they would be great to get a little bit of an extra push to founding especially since Egypt tends to run tall. I also do wonder what would happen if you decide to annex a city with the UB destroyed, generate two flax by building it, raze the city, and build an brand new one on the same tile? Probably not worth the effort but would be funny to see a river of flax. Still, neither really synergized with Egypt’s kit (not nearly as much as war chariots which were a godsend for early wonders). Maybe it would be cool if either of them had an attribute that scaled up based on the number of wonders you owned (or number of wonders created in that city)?
