Earth style:Sand EarthQuake(punch the ground, earthquake appears, sand comes
up, making Sand Coffin easier to use)
hmmmm........good jutsu, needs a better name.......Earth Style: Rising Buried Desert? Yeah, that works.

Ninja art:Chakra Needle Barrage(Needles made of chakra exploding)
hmmm......I suppose 3 shinobi using the technique simultaneously could provide 360 degrees of needle on one target.

And now my own thoughts:
What if you froze blood into the shape of a blade? Would it be stronger than normal ice due to it's iron content?

Wind style: Dragon storm jutsu!
(pretty self explanatory)
