Obito's Bijuus will blast the Kages to hell , he can deal with edos and also Madara can take their souls , so it's not only Itachi who can "seal".
don't forget that we have shisui here , he can control them using KA.
the bijuus wont do much,tbb's are nothing here since both sides are edos,not to mention that the tbb's would also hit the uchihas in the battle field.
Madara has showed only preta,he never mastered the rinnegan,neither he,nor tobi have any sealing jutsus sjown,and to take the sould,they need to touch the person,and leave themselves vulnerable to the other attacks.
We have 17 edo kages here.
Muu and onoki as edos will spam jintons on everyone,not to mention the first as well.
Raikages are all limitless in chakra,there are 4 of them,so we have 4 raikages running around with raiton armour
kazekages are the worst.each of them can control the environment,now that they are edos,they can conjure limitless amounts of gold dust,sand and iron sand from the ground and surroundings.

gaara can do that ten times over,alongside the other kazekages,not even counting the first and second kazekages.
All the known kazekages can fly,all the known tsuchikages can fly,mei as an edo can make the hidden mist very large by adding continous chakra through it,neither a sharingan nor rinnegan can see through it,the entire team uchiha will see nothing but her chakra in the mist,they will basically just see a cloud of chakra around them,madara himself was affected by this technique,the 2nd mizukage does clam genjutsu,further removng their sensing abilities,and giving them mirages of himself and the clam whereas the kages can pinpoint them and attack.
Onoki was able to immobilize 2 susanoos by touching them,as an edo,he dosent have to worry about getting hit,except by itachi,so he can just immobilize their susanoo while muu goes invisible and does the same to another susanoo,all this being done in the hidden mist clam mist genjutsu illusionary mist of the mizukages. Yagura is a perfect jin,and can use his 3 tailed body to roll over the susanoos.
Muu and onoki being edos,need no help to make full sized jintons,which destroyed 25 susanoo clones.
Muu as a sensor can take advantage of the mists created by the mizuages to find the chakra rods in the bijuus,allowing the raikages to pull them out,or the kazekages could just seal them in a giant pyramid of sand gold iron sand. All the uchihas aside from madara get flung out,especially as the 3rd and 4th kazekages need no prep to control the environment.
The 2 raikages known,have vwry strong bodues,this coupled with the edo ability,gibes them enhanced regeneration,km naruto pushed hachibi's tbb,A is much stronger than km naruto,while hachibi is stronger than those bijuus.
Muu,gaara and most likelt the other kazekages are sensors,KA is only useful on a one on one,and with no intel,shushi dosent even have susanoo,how does he survive the waves of sand,gold etc coming at him contiously?.
Since everyone on team uchiha use rinnegan or sharingan,the mists created by the mizukages would render their eyesight very fuzzy and unable to locate their opponent,not to mention joki boy.
With edos on both sides,kages win
