Well that was obvious for an opening. 
As I see you throw a kunai with an explosive tag on it, I throw 2 kunai at it. 1 to deflect it, and 1 to hit it in the angle it makes, so that it flies back at you. If you continue with the shuriken, you will explode (O_O).
I then make two clones. C1 left of me and C2 right of me. They more in an arc towards you, both at the same distance of you all the time (so they would be mirrored) and both are throwing 4 kunai at you. They both multiply them to a hundred kunai. They continue to run at you in an arc, while I watch your every momement.
(Basically, you have a kunai with an explosion tag coming at you, and about 208 kunai, normal ones.)
