Kind of bizarre we haven't seen any ten shadow techniques. I'm sure Gojo can blow majority of them away, but at least it'd give you something to occupy him.
And hopefully we are almost done with the domain stuff as well.
10s shikigami except Mahoraga has been utility based so far.
Sukuna doesn't need them cause he already has anything they can offer, and in a much stronger scale too.
Divine Dogs, Max elephant, the Bull etc - Strength.
Rabbits, Snake, Frogs, Nue etc - Dexterity
Madoka Deer - RCT
Sukuna vastly out performs any of these with his own CT and techniques.
Mahoraga is the only useful one for any top tier like Sukuna or Gojo.
And in case of Mahoraga, the best chance to use it would be at the start of a fight. The fact that sukuna didn't means he's confident he can take out Gojo without it. And so far, he hasn't been wrong.
I think 10s shikigami won't be used at all. Sukuna still has CT, Open, Yorozu gift etc to use. And he might have his Cursed tools from the Heian era stashed away somewhere too. He could maybe access them using Open or even 10s storage technique.
