Mine would be called Death Cloned Shuriken jutsu.Here's how it works.
User inserts chakra into its own palms.This takes 5 seconds, then it forces the summonings to come to the user and suddenly turn into shurikens. Then the user gets the shurikens, insert chakra, and throws it. While in midair, it makes clones from the chakra inserted. Once it hits the enemy, the enemy will be injured in its chakra points.
Mine is simple. My choice of jutsu is, a jutsu that can counter all the techniques. For example if anyone will use a jutsu except the user he/she will die automatically. And I like to name it as Eternal jutsu. Hehe..
