Since i haven't affected his hearing, a silent jutsu would definetly be preferable, so i would either just stab/slash him with my sword or a kunai, or i would use.
(Katon: Haisekisho) - Fire Style: Combustion Ash Cloud
Rank: B
Type: Offense
Range: Short/Mid
Chakra Cost: 20
Damage Points: 40
Description: The user spews superheated ash from their mouth. The ash is hot enough to cause third-degree burns on the victim. Because it's composed entirely of ash, it stays in the air around the victim like a cloud. If the user clicks his teeth, the stagnant ash will ignite, creating a violent explosion.
since the clones sense of smell is cut off, he wouldn't notice the ash, until it was close enoug to him to be lethal, i would simply blow it up.
