This seems like it would do well in pve because normally your whole team goes first, then whole enemy team goes instead of normal move order. But i cannot imagine this working at all against players in convoys or sage battlefield.
Naruto goes last and it's very obvious what you are planning, you are asking to get interrupted/acupunctured and like 90% of players run at least one of these, normally on position 1 or 2. Also this has team 0 defense against debuffs, if they get you it's over.
I would recommend having Naruto go into position 1 or 2 so he moves earlier and have the water main go last with heal so you can have some debuff protection, you don't really need the shark bomb since you already have 3 aoe damage mysteries so you should always have one ready.
