Agree, Seeking Arrow works. It even works in case of many commanders - it just needs to be numerous enough. But I prefer to use it before big battle to soften up the enemy - not against army with 1-2 commanders which then doesn't arrive (unless my forces are inferior to this army, of course). Still, opportunity cost between having a commander with anti-missile protection or many commanders with no protection may vary depending on your situation...
