Kabuto is great. Hinata/Kakashi is great for combos but Kakashi is not a tank at all - he dies too fast. Once you're a level 50+ you can get summons, which fill in the gaps in your combos. Until then, test your moves against the Kakashi clone. Speaking of moves, probably the second of the two available to you, but I'm not lightning so I don't know what each one is.
