Go for 3 star Sasuke and swap it with Kakashi so you can have a repulse which trigger Hinata's acupuncture! Also you c*e shizune which can chain their combo all together. Replace it once you get Karin/Kabuto.
As for your lineup, I would really prefer to use GNW Neji over Hinata. Reason being because most lightning main and fire main will outspeed you in mystery casting and Neji can be used to prevent that from happening by acupuncturing them in turn one and acupuncturing the other in turn two.
You basically can chase up to 6 combo, utilising every chase that your ninjas has. You need to acupuncture the correct target to prevent your ninjas from taking huge damage. As you are level 40, you don't have access to summons which really can help alot in chaining chase together. Start farming for tobi frag if you haven't from the group store, he is really good right now.
