Work towards getting Hinata 2* and sasuke 3* if you haven't already , and also gather those tobi fragments.I'm level 53 and the team I use is working wonders.
Wind Main - Sasuke - Hinata
Tobi - Wind main clone - X
X - X - X
Talents : 2-2-3-1-1
Summon is only optional ,it works without it too : Shark

Until then , you might also not spend every seal scroll you get and keep them until you have ten and trying your luck for a free 3* which might be Baki who is very useful later with Gaara.
