its nothing that grand but i was just thinking to myself and with Naruto's mastery over the shadow clone technique i think it would be quite cool if he learnt the shadow shuriken jutsu..
just imagine if naruto could use the technique and he threw a rasenshuriken... imagine if he could use the shadow shuriken technique to make a load of clones of his rasenshuriken...
since naruto's specialty is shadow clones.. its quite the realistic jutsu he could learn... not to mention one rasenshuriken suddenly turning into 40-50 will catch anyone off guard...
before anyone sais its not possible to clone a technique dont bring this up unless u have definite proof.. i mean naruto could turn himself into th very technique itself so what stops him from cloning it.. its not that farfetched
