Aztecs

I've recently got back into the game and love it! I've been giving the Aztecs a try but I feel like if I dont win early I might as well quit. Aztec infantry are just shredded and it has been starting to frustrate me. I would like to know how Aztecs should be played late game along with card recommendations and maybe unit compositions. It's really great to play this game again and I'm excited to be back!
