I mean really Sasuke has Preta Path which makes more jutsu useless, yet he has only use that jutsu only once against Naruto. Imagine the possibilities like Sasuke uses Kirin and hits himself, but instead of hitting himself it gets absorbed by his preta path.
Or what about Sasuke asking Naruto to absorb his Sage Mode or RSM to learn to use either of those two himself.
