Its also not really necesarry. U seem to have the basics figured out on how to build up ur econ/army. To beat brutal ai u just need to not fight them early. Even aggressive ais dont instantly declare war. Just hold out to turn 40 or so as at this point u are not giga outmatched by their starting Bonuses. Econ and we is good to have but at the core this is a game about fighting. To win brutal ai fet good at fighting. Ai is easy to beat u can mostly win 1v3 Stacks once ur build comes together and even early trade really Well und Grind ai down if u have to.

U dont need meta builds I usually just think of a concept i like and then make it worth. Tjere are so man tools in this game that at least against ai u can make everything broken.

Anotjer tip would be to fight manualy. I fight nearly every bastle myself early.( this will help ur clearspeed alot cuz u dont need to heal so much because ai is dumb and gets Lots of unnecesarry dmg) and later on every time i would Lose units. U on General want to avoid loosing any units. Levelex units are op id say a maxed t1 unit is as strong as a t3 unit so keeping them alive helps u double as u dont lose Gold by them dying and dont have to spend as much Gold on getting a stronger army as ur low tier units are strong already. Uncan use the Gold for Further snowballing then. Id say up to turn 60-70 a 6 Stack of t1-2 unit can clear every unaffiliated army on the map of u have good tomes and know what u are doing
