The reason it's no longer used is probably because it requires preparation? And also because it requires a hand sign with 2 hands? Is that why it's no longer used in Boruto? That's the most reasonable explanation for me🤔
Rereading kaguya arc sucks cause not only kaguya but they randomly lie/retcon about Sasuke’s ability IN THE SAME ARC, use the cool techniques once or not at all, the fight itself just isn’t good, and a lot of other BULLSHIT
Just got reminded how annoying it is.
