Hmm... This seems a bit hard sempai! O_O
Sigh, no whining about it I guess...
I start to summon a big amount of Suiton Chakra, I then start concentrating on it and perform the hand seals you've just shown me. I use shape manipulation to shape it like a shark, and send it at your clone to attack it.
I hope that was a good and big enough shark O_O.
*poof*

This jutsu very much simply solidifies the moisture in the air around the opponent into water, and cover them in it do they drown. It can be used as a source of water, and you could even use it to summon water based animals onto the battlefield. *shows you hand seals* Do it
