The essence of sealing techniques lay not in overwhelming power, but in their use of the Shinobi World's rules and their highly efficient mobilization of every available force.
Though they were not like the Mangekyō Sharingan, which directly used Yin Release to manifest spiritual power, nor like the Rinnegan, which could wield space, gravity, chakra, souls, and more without delay.
Sealing techniques used runes, a unique kind of "language," to indirectly pry at the underlying rules of the Shinobi World. Their combat power was not as direct as the secret techniques of the Mangekyō Sharingan and Rinnegan, but at the root, in the finer details, they were actually the same.
Otherwise, how could the Uzumaki Clan have used sealing techniques to create something as miraculous as the "Shinigami"?
How could they have sealed the tailed beasts and created strategic weapons—the Jinchuriki?
How could the Fourth Hokage, Minato Namikaze, have used specially made kunai to seal spatial coordinates and perform the Flying Raijin Jutsu?
Not to mention Dreamplay, the simulated world Mizuki had created directly through sealing techniques. Its potential was enough to overturn and replace the Shinobi World.
If a sealing technique master could fully play their role, the subtle assistance they provided was practically all-encompassing.
Mizuki could use sophisticated barriers to set up battlefield traps, vastly increasing the Allied Forces' combat strength. He had also achieved much in medical logistics; short-range spatial transportation arrays ensured severely wounded soldiers requiring emergency treatment would not waste precious rescue time on the road.
And there were many more examples besides.
Now, however, the enemy had acquired a roughly equivalent power. It might not be as comprehensive or useful as Mizuki's sealing techniques, but it could at least offset the advantages brought by his exceptional sealing techniques to a considerable extent.
