Maybe Statue of Zesus is the Anti-Cav buff? They get a whole Wonder to make them cheaper... AC do still need a buff. I think the key thing would be just improving the base strength of some early AC units, and giving AC a promotion with defence v ranged. Beyond that, they would do well being a bit cheaper. I’ve suggested Walls maybe giving a production bonus for AC (which is along the same idea as the SoZ in a way). That would make AC situationally cheaper and tie them up with defensive infrastructure more. You could instead tie the bonus to other infrastructure - warlords throne perhaps, or just encampments. Alternatively, you could play around with how flanking and support works for AC, again to make them a bit better situationally. ZoC v Cavalry is a terrible idea. There are plenty of posts about it. Can’t muster the enthusiasm to go through it again, but yeah part of it is making Lt Cav pretty irrelevant.
