Obito absorbs Sasuke into his dimension and leaves him there.
Pain could easily Universal Pull Sasuke towards Obito/Orochimaru/Himself and ultimately take his Soul Out while Obito and Orochimaru team up to prevent him from attacking any further.
If Sasuke kills Obito, Orochimaru brings him back with Edo Tensei using one of Pain's Six Paths and Obito is Immortal asf.
TBH, All of Sasuke's Rinnegan's feats aren't even explained as of yet.
Madara said Sasuke posseses the Same Rinnegan as he does. Assuming that's true then Pain won't be Universally Pulling Sasuke anytime as Sasuke is capable of Limbo as well, meaning Limbo Sasuke is going to be causing a ton of havoc.
This also means Sasuke can absorb all ninjutsu to goodbye Orochimaru, and possibly Obito's Kamui since it is still classified as a ninjutsu.
Seriously, Sasuke takes this Mid difficulty possibly high difficulty.
EDIT: Is Orochimaru starting with any edos prepared? Because He isn't just going to ressurrect Obito and Pain if they fall. not without bodies and extracting DNA. Pain would be the quickest one to ressurect any of the fallen. Seriously. Sasuke has Rikudo status now. He is in a teir above theirs. I see them giving him trouble, but I don't see any of them winning.
