Again , I Said They win Because Itachi is an Edo , so Even if Onoki makes Susanoo heavy and He can't Move , He will Just Have to disactivate It , or Kill Himself and Regenerate
and Itachi can Keep Susanoo all Fight Long , and If Onoki will get Close He will be Sealed.
..Sasuke's Lightning > Gaara's Sand , and Chidori Nagashi will Make Sabaku Sousou and Sabaku Kyuu Useless because it will Make his Body electrified.and This is Not a desert , so he can't Control the Battlefield
Gaara attacks Cannot penetrate Susanoo , But His Only Chance here is To pull Sasuke out of The susanoo Like he did With Madara ====> and Then ? Sasuke have Enton Manipulation too , so he is so Damn hard to Touch or to Get close To and Have many Genjutsus To Make Gaara in a Chaos and Finish Him
I Understand That the Kages have a Big Chance of Winning Here because of A but if they Do it will Be Very High Difficulty
as i Said ,
If Itachi isn't an Edo , He and Sasuke will Get Obligated
If it Was in The desert , They will Also Get Obligated
onoki dosent need to make susanoo heavy,he can just use jinton on that,he will make itachi himself heavy,like against muu,and itachi wont be able to kill himself cuz he wont be able to move,itachi might be an edo,but he has 4 kage level shinobis facing off against him,and a sand clone to use sand to seal him.
Sand isnt weak to lightening,as gaara blocked v2 raiton A with bijuu level chakra concentration around his body like it was child'd play and with little sand,he hid his sand in electrified water to catch madara. Sand is also an insulator,so it isnt weak to lightening at all,chidori nagashi means that sasuke wont move around a lot,and sand pyramid easily stopped oil hydrification,which is it's true weakness,so chidori nagashi wont help at all,and sand arms will still hit sasuke regardless of CN. Gaara controls the environment regardless of a dessert,because he can make a dessert in one panel easily,and his match with kimi proved that the location dosent really matter,so the fact that they aren't in a dessert dosent really matter. Gaara doent need to priece susanoo when he can easily attack from underneath and get sasuke,he can make sand bodies appear quickly from the ground like how he caught the kages at once. Enton isnt very useful as it cant burn through gaara's sand and gaara can easily use it to attack sasuke,gaara himself isnt touching sasuke,his sand is. He dosent have to get close to kill sasuke,and enton isnt solid,sand will go through it and still get sasuke once he is pulled out or just attack him from below easily.
Gaara can turn nearly any location into a dessert,and he was able to turn a rocky area to a sand box in one panel,both their susanoos have holes underneath,and onoki can use his earth techs to attack them as well,gaara and onoki could take itachi while the others and a sand/rock clone handle sasuke or gaara could handle sasuke while the others and a sand clone handles itachi.
