What is the most competitive and interesting Cavalry-centric army? I'm looking for to start an elite(small model count) Fantasy army with a focus on cavalry models but I don't know enough about the game to choose an army. I like cavalry models the most which is why I want them to be a central part of my force.
Any suggestions? I'm aware that Bretonians are the go-to army for Knights but I wanted to explore other options as well.
