Suggestions for Fireworks ninjas:

-Suit Gaara (almost no one has, not meta)

-Christmas Temari/Shikamaru/Summer Gai/Asuma/Suit Iruka/Swimsuit Raikage (possibly too new but not many people have bothered to buy these, no meta use)

-Hokage Tsunade (formerly meta ninja, still possibly useful, superseded by newer Tsunade variant)

-normal Hiruzen/Tobirama (few people have these unless they randomly got them in a mission exchange pack, not meta)

-final 40 frags of AOG Konan

-Danzo Izanagi- (super rare, not particularly useful)

-Edo Han/Utakata/Fu (since we can't get their proper non-limited treasures and can't grind them out in survival/3v3, not meta)

-Young Nagato (very rare, not as good as SB Edo Nagato)
