New to the game and wanted recommendations

Hi guys, so yeah im new to the game and wanted some options to play in midlane (usted to be jungler but its rough out the haha)

So the champions ive been playing are these:

-Xerath
-Veigar
-Ahri

I like skill shots, but im open to any champ. I mainly wanna focus in 3-5 champs to get better through time.

I love xerath so i think I already have one set, but need other options.

Thank you!
