I cant think of any scenario where Kabuto (clone/healer) would be able to replace Hinata. (evasion/tank)

His decoys can help mitigate dmg but they are easily killed in AOE and you're left with Kabuto who is very squishy.

I'd say kabuto for sasuke. At least you have some healing and clones to protect kakashi

I would take Hinata out. and replace with Kabuto. Plus you will get better combos with that setup.

For your team I would recommend keeping hinata, or if you really want to have kabuto on your team,
take out kakashi or sasuke.

The reason for that is that without hinata who is the tank of your team, your front row will be very squishy, and also most importantly, you'll have no control in your team if you remove hinata! her chase attack allows you to prevent your opponent from taking actions (standard +mystery attacks.)

So even if kabuto may give you a slightly higher combo, it cannot makeup for hinata's crucial role in your team.

I would suggest removing Kakashi for Kabuto. You do need a tank and Hinata is a very good one, also Kabuto's human experiment will trigger 2* Sasuke's resistance and ninjutsu cure tag boost.

use zabuza, sakura and haku or i use sai kabuto and kakashi works hella good

No that isn't true only because you are lightning, now if you were Earth that would be a different story. In anycase for your set up I would replace Sasuke with Kurenai, but I don't play Lightning so what do I know?
