The lineup is still good (not godlike like it used to be before Shishui and GNW treasure appeared) . What i did to piece him together was get 3-6 frags of him whenever he appeared . If you don't have many event-only ninjas (like Masked man , Sailor Sakura , Shishui , Kushina Habanero , Edo Deidara etc) and like Deidara , get him . But if you have a big ninja collection invest into power . 90k+ BP is easy these days , even for f2p (with good recource management ofc)
