*As I did previously, I begin molding chakra while closing my eyes in concentration. My imagination is certainly critical for properly performing these techniques. In my mind, I imagine your clone and I standing in an identical environment, with me remaining stationary and your clone still running at me. In my visualization, a flurry of leaves appear out of thin air and swirl around your clone, completely obscuring his vision and stopping him in his tracks while he wonders what's going on. Then suddenly, the leaves clear away and in front of him, instead of me, there stands a visage of his greatest fear (a cat or the inside of a plane, I haven't gotten around to watching Supernatural yet, so idk what Dean is afraid of). Upon seeing it, your clone is frozen in his tracks. At that point I open my eyes after having molded enough chakra and perform the required handseals. I proceed to release and channel my chakra into the clone who is running towards me, casting the created illusion unto him just as I have done to your previous clones. Once the Genjutsu takes effect, the leaves will begin swirling around him and he will likely stop in his tracks to discern what is happening. Next, his greatest fear will appear before him (observable from screaming, shaking, sweating, etc). At this point, while he is distracted by the illusion, I toss an ordinary kunai that hits your clone dead in between his eyes and kills him. He dissipates immediately afterward.*
Advantages: You can take advantage of the moment where the opponent can't see you (because of the way the leaves obscure their vision and you disappear afterward) to attack them freely. Additionally, the user will also be able to take advantage of the opponents hesitation upon seeing what it is they fear most.
Disadvantages: I imagine it's not all that difficult to see through this technique as an image of what what you fear most magically appears in front of you in the midst of battle. I believe the absence of wind is another thing that can be used to deduce that one is under the influence of a Genjutsu. If this technique was used against me, even if I didn't suspect a Genjutsu, I would still inflict pain to myself to prevent myself from freezing up/passing out, similar to what Sasuke did when faced with the Killing Intent technique -- the fear in itself is a reason to break out of this technique, albeit inadvertently.
