Advantages
1.) No hand seals
2.) Has the power to carry things like rocks, so it would also have the power to carry other things of similar weight
3.) Lifts my opponent, leaving them open for another attack
Disadvantages
1.) No long range
2.) Streams require constant concentration, leaving me vulnerable
3.) Temporarily gives my opponent the height advantage
Counter
Because this technique takes constant attention, I would use a technique like this:
This is because, it has no hand seals, it attacks from a blind spot, and he would have no time to counter because of the technique that he is using. And to do this, all I have to do is slam my hands on the ground, so that is totally doable before I am lifted. Yes, I may be pelted by a few rocks, but in the end I would have done the most damage.
Combinations
Since this technique has the power to pick up rocks, I don't see why it wouldn't have the power to pick up ninja tools as well. So I would lay out several kunai knives before doing this, so they get picked up and shot off at my opponent as well. I could also use this to lift my opponent into the air, so that during their free fall, I can accurately predict where they are going to be, no matter which jutsu I decide to use.
Performance
Trunks stands mid range from your clone, and concentrates his fuuton chakra. He then uses nature manipulation to turn it into wind, as he blows a powerful wide spread gust in your clones direction. It would lift up various rocks and pebbles of differing sizes before eventually lifting the clone as well. Not long after being lifted, the clone would begin to be pelted with the rocks and stones, travelling at high speeds. After a few moments of this stoning, the wind dies down allowing the clone and rocks to fall.
