This is the formation that I'm currently using, and it got some decent combos (11 combo hits when it is initiated by a knock down). By second round, this formation c*ually generate enough chakra to use the mysteries of chiyo, SN and the MC so if you focus on the character in the oponent's side that have the least health, you can probably kill it.
I use tsunade to help me last longer in battle and remove debuffs (specially good when i'm up against fire mains).

Summon: repulse -> low-float.
Chase: primary lotus.
