Which kind of army is working better? Do you have any suggestions? Please, post them here?
P.S. I'm in s19, anybody can post screenshots of top alliances and players (title and prestige) of s17-18-20?

Your best Army is the army that works for you. Mathmatically I'm sure someone can prove a full on catapult and cavalry army is the best. For me I also incorporate the archers into mine because of the rang attacks. They are a lot weaker than a catapult but if you have around 20k worth they do a lot of damage to a weaker foe. I'm not trying to sell the archer I'm just saying I use them in mine. You can hold a lot more archer than you can catapults. Plus they are faster than catapults.

there are guides in the guide section, to try to help you decide which army to choose.
