You could try my fodder team. Work well for lower level checkpoints. Could clear 8 ~ 9 checkpoints with less than 10% health lost:

Kabuto/Karin Kakashi/Guy x
Sakura Naruto x
x x x

If the opponent relies heavily on combo, then you could try:

Sasuke Main Hinata
Kabuto/Karin x x

Shift your ninjas around helps too.
