The best way, is to utalize this when you know they need to use a certain ranked technique so that it hinders them. For example I can accomplish this by releasing a high ranking technique that they would need to counter, with a high ranking technique them selves. Being a sensor it would be quite easy for me as I would know. Then by casting this as they are about to perform. It cancels their S rank techs as they need to break the genjutsu first. That small opening is where the jutsu is effective as they won't have too much time left to counter after breaking it.
Moving onto the clone.
As I see your clone and have been effected by this jutsu. I take revenge on the poor fella. I quickly perform two hand seals Dragon → Hare. Then release the chakra into his brain to disrupt his own chakra. He begins to see blurred vision as well as getting a headache from the confusion of the shaking. In the meantime him dealing with my shaking I quickly release a strong wind attack that is intagable to the naked eye. Leaving him vulnerable as the wind travels fast towards him.
Poor Clone! He dies.
