Water Deck: Comments & Criticism Welcome

[Kyoujin]

Here's the Water Deck I've managed to finally build after many retoolings and restructures. It seems to work very well, and I haven't had any difficulties with its triggers:

Ninja

Haku (Childhood) n614 x3
Anko Mitarashi n622 x3
Rashomon n874 x3
Haku us035 x3
Zabuza Momochi (Younger Days) n874 x3
Orochimaru n353 x2
Sasuke Uchiha n1005 x2
Kisame Hoshigaki us078 x2
Kakuzu n786 x2
The Second Hokage n822 x3

Justu

Multiple Striking Shadow Snake j733 x3
Chidori Stream j575 x3
Water Style: Water Dragon Jutsu j611 x3
Water Style: Giant Vortex Jutsu j034 x3
Water Style: Five Hungry Sharks j460 x3

Mission

Visitors from the Darkness m295 x3
Invasion of Akatsuki m625 x3
Unstable Ground m445 x3

Reinforcement

Kakuzu (Soul Form) n989 x1
Sasuke Uchiha (State 2) n934 x1
Four Souls of Kakuzu n841 x2

I'd really like to replace Water Style: Five Hungry Sharks j460 x3 with Water Style: Water Shark Bomb j500 x3, but I can't get my hands on any.
