Yes. Well Ninjutsu is by the usage of regular chakra which is flowing throughout our pathway system all the time. Using the chakra within us allow us, as you said, to perform a great variety of techniques. Regular is also the fundament of all other kind of chakra natures.
Now, well, according to our RPG Ninjutsu --> Regular chakra, is weaker than elemental chakras, meaning that if two S-ranks of each should collide, the elemental would win. Though theres some advanced versions which is a pair with elemental chakra, however it would take too much time saying this one can't, this one can, and so forth. So basically, keep it as I said, unless you get told otherwise(Preferly from a mod, lol.)
Nonetheless. Let's procced. What was the last techniques you learned? Please copy paste them all into a spoiler.
