If you can, use sasuke 3 star instead of kakashi. Sasuke's repulse will lead to hinata's acupuncture which is really good combo. And use 'enhancement of lightning ninjas' as your passive talent. I don't know Iruka's chase so I won't know how the overall combos will turn out but I can assure you that the combo will be much higher with sasuke than kakashi. If you can't be bothered to upgrade Sasuke to 3 star, you c*e zabuza instead of kakashi. Zabuza still gives repulse and spawns a clone with same max HP as him while kakashi spawns a clone with half of his max hp. This post was last edited by 165***@facebook at 2016-8-4 18:18

So basically:

1. If you aren't using the lightning team buff talent, use it.
2. Swap kakashi with zabuza or sasuke (I would recommend sasuke more).
