You're joking,right? Naruto's clones and rasenshuriken against Base Sasuke's arsenal,superior battle skills and intellect is like putting Skypeia arc Luffy versus Prime Whitebeard.In other words, it's not even a competition.Base Naruto is a one dimensional character who only has close range ninjutsu and inferior taijutsu skills to Sasuke.How exactly is Base Naruto going to defeat an opponent who has mastery of all ranges of jutsus, superior battle skills and strategic ability , along with speed and reflexes(thanks to the sharingan)? Naruto can't even throw the rasenshuriken in base.The more realistic match up would be Base Sasuke versus Sage Mode Naruto.
Learn to read, you damn fool.
1. Base Sasuke means Sasuke without Sharingan.
2. Sasuke doesn't have that big arsenal in his base form.
Superior battle skills? How so ? They are both equal in taijutsu, Sasuke has only a slight advantage on intelligence and speed. Cause Naruto is a fighting genius, same as Goku in DBZ.
3. Rasen Shuriken can vary from close range to long.
4. Base Sasuke has only a few long range techniques, so that wouldn't matter that much. Naruto also has a nice strategy with his clones.
Since base Sasuke has no Sharingan, his reflexes ain't that unbeatable. And Naruto is able to throw Rasen Shuriken in base.
SM Naruto even shits on MS Sasuke.
