Not a bad selection of ninjas. You've got some pretty decent options, but without summons, you need to play to a lineup that you can pump high damage with.
Personally, I like having my main line be the real damage dealers, then having two tanky lines, or one tanky + one clone lineup, so think about something like this:
X - X - X
Shizune - Kiba (Great Ninja War) - X
Sasuke - Main - X
Chidori Blade Shadow, Lightning Assassination Sword, Lai Giri Decapitation, Anbu Special Tactics, Bloodthirsty
Great combo chase, and even if your main dies, you still combo with the rest of the team. Plus having Shizune to remove debuffs and double the heal from Anbu Special Tactics is super useful. Just make sure you move this lineup to Top / Middle / Bottom, depending on what enemy teams your playing against, and insert it against either the clone-heavy team, or the team that's weak to single target damage.
Next up...
Kakashi - Neji - X
Zabuza (Regular) - Guy - X
X - X - X
Good combo potential, plus the heal from Guy and the dodge from Neji will keep this team alive for a while. That, and the clones will tank a lot of damage before your guys start getting hit, and double interrupt will really put a hurt on the enemy teams abilities.
Last team is a bit tough, but I'd make it a Chiyo-focused, fully defensive team, so you get to use her Resurrect ability more than once (hopefully)...
X - X - X
Sakura - Zabuza (7 Ninja) - X
Chiyo - Hinata - X
It's not the best combo damage team, but having Zabuza move first will let him counter a decent number of abilities with Water Prison, and between Sakura and Hinata, you'll have enough tank damage to survive for a while with Chiyo in the back.
Test them out and let me know what you think :)
