You should realy taking it serious about getting asuma wb or getting that gaara 3 star.

Best lineups would be Lm danzo, iruka asuma wb with rhino summon skills 3.1.1.1.2

Or you could try the wind main with sage Naruto, gaara(3 star at least) and iruka/kurenai full skill breackthrough. Although kage gaara would work as well but that means you need iniative so not best option.

The meta water lineup I good but outdated. its easily countered now. another good lineup would be roshi, fuguki (fat guy from GNW treasure) water main and sailorsakura/kurenai ( full skill break)

I wount start telling you fire main lineups because you actualy need some strong ninjas there and ofc you realized it Shisui, masked man, itachi anbu, and other stuff.

For Earth main again you have a problem because best lineups would be shark kisame, edo deidara, pai jigokudo/tsunade hokage and earth main or edo deidara, jimpachi, earth main, jigokudo/tsunade hokage or roshi, Naruto kurama mode, earth main, killer bee seven sword style. ( but those are already to far for you. so best try wind and light main lineups for now.

Also if you get shisui and anbu itachi there are good lineups for light main as well with either asuma wb or iruka
