What you just said is typical for every shonen lolYou seem to be confused, having similar elements and straight up mirroring are two different things.
Black Clover essentially Is Naruto, just switch out Ninja for mages, Hokage for Wizard King, Edo/industrial era for Medieval/fantasy era and so on.
Don't get me wrong, it's an alright manga, but the amount of similarities goes beyond typical Shonen elements.
Let's say One Piece...change the pirates with Ninjas,Pirate King with Hokage and so on and you get Naruto...
