You don't lose any fighters, you lose all your archers, knights, and mages instead.
I wish I had the unblockable, unavoidable, unnegatable, irresistible, unreflectable ability to control the minds of sentient beings, activated at will by me and only me, indefinitely, regardless of range, mental state, gender, race, creed, training or any other status short of death, whilst still being able to control my own body and costing me nothing in return. (I'm sure someone will corrupt my wish, but I had to try some BS like this)
