I have the same formation. Though I've realized it's not really based on the way you setup your Ninjas. It's mainly on your skills and equips on them. For Blaze, Try to get her level 25 skill. It will improve your attack.
This is indeed an amazing beginner combination, i write a guide about it here http://forum.naruto.oasgames.com/en/forum.php?mod=viewthread&tid=205&extra=page%3D1
i like use mirror return in pvp it useful , if you use fire style dragon , sakura will auto use heal at turn 1 when your hp are full in arena This post was last edited by 174***@facebook at 2016-7-23 12:07
it's a pretty good lineup but this one is i think a little better: you can keep naruto and saskue ( sorry for spelling mistakes ) where they are but move sakura behind saskue and put main in the very back where sakura was. This lineup is good because naruto and the clones will protect main and saskue from getting killed so they can reck your opponent and if the clones get killed before you can defeat your opponent you have sakura to heal.
that's an ok lineup but i think this is better: you can keep naruto and saskue where they are but just move sakura behind saskue and main to where sakura was before. This is a good lineup because naruto and his clones will protect main and saskue from damege so they can reck your opponent and also if the clones die you can still use sakura to heal.
