Hello, first things first i would collect and work for Obito Rage Mode 4 stars. Since you already have the base that is like job half done. There is a great support there, Kisame Swimsuit. But there is also Han. If you wanna make *together change. Pos1 Han, Pos2 Kisame and Pos3 Yagura can be helpful. However if you want something alt, you cann go for Mei pos1, Yagura NY pos2, and grab Genma 3* from myoboku trials and get chase damage and proper aoe from Mei for ages. All and all there is plenty of potential here. But still we head back to beginning the path to Obito 4* is the easiest for now.
