The point of March of the Ancients saying it’s used after selecting your Warlord is so you can’t use it to make a Dreadnought a Character and then choose it as your Warlord. That’s it.
This.
Just like Strike from the Shadows, you can use it as many times as you have
CP to do it.
Have 6 Dreadnoughts in your list? If you want to spend 2/3rds of your
CP before the battle starts they can all be characters.
It only specifies that it has to be after Warlord choice so you can't make a dreadnought a character and the Warlord, and thereby make it nearly impossible for your opponent to claim Slay the Warlord.
GW did that on purpose because they know very well how tough they just made Iron Hands dreadnoughts.
Every pre-battle Strategem that can only be used once specifically states that in the wording.
If it does not say so, it can be used multiple times.
