I personally like

Itachi Asuma x
Kabuto Main x
x x x

Of course you c*e it with nearly any main just by adjusting talents and summon. The idea is to spam Asuma's mystery each turn with 0 CD and 0 Chakra consumption since your chakra will be at 100 on round 2. And if you're lvl 80 Lightning Main can cast his mystery for free too provided you have 50 or more chakra which you should if you can keep Itachi's barrier up.
