Depends on what you are fighting and why are you using Spire Horn warriors? Do you have any other units? What type of Commander(s) do you have? What type of spell levels?

I'm not flawless, but as is common to some people who play this game, they ask a question; don't like the answer or it doesn't fit what they wanted to do; and do not attempt to find a way to circumvent it and instead say broad generalizations like "I've played a Mammoth nation, I want to play a flying one" that don't take into account the whole and only a thin perspective of what they can't seem to get to work.
