Tsikhes suck. They arrive too late in the game, it requires earlier walls which you don't really build in every city, and it becomes unbuildable once you get Urban Defenses. That's why I made them an Ancient Walls replacement.
Features:
1. Tsikhe replaces Ancient Walls. Compared to Ancient Walls, they have:
70 production (10 production less)
200 HP (100 HP more)
+1 Tourism on Conservation (same amount)
2. Decreased yields from +4 to +2 Faith like a Shrine.
- This is to balance them since you get them early.
3. In a Golden Age, Tsikhe still provides additional +4 Faith and +3 Tourism.
