There is a lot of info on what champs are the easiest to play if ur new and what champs are the hardest in the game.
No info at all on what champ pools to move through as somebody progresses through skill at the game.
Beginner:
Intermediate: ???
Expert:
lol Here'a better list lad.
Easy champions
Intermediate
Harder
The ones that are missing belong in the mid between easy and intermediate
There's no list of "intermediate" champions because it's all purely subjective.
Most people can agree that champions like Garen, Annie, and Amumu have extremely simple, straightforward kits that are easy to understand and easy to use/master.
Most people can agree that champions like Riven, Lee Sin, and Yasuo have extremely difficult kits that require a high level of mastery of game mechanics, knowledge, and mastery of the champion itself along with high reaction times and manual dexterity. Most people are just incapable of playing champs like those at their full potential.
But what makes a champion "intermediate" is too subjective to be worth anything.
Intermediate
For example is full of himself if he's trying to push his opinion as fact. Most people would consider Vi one of the easiest junglers to play since she has a single skillshot, a passive as a skill, and a point-and-click ultimate that you can use to close the gap and use your skillshot at point-blank range with zero chance of the target dodging.
Considering the fact that Zoe's winrate starts at 44% at low elo and raises all the way up to 51% at high elo, she should most likely be considered an expert champion because of the difficulty of her kit.
Warwick is another jungler I'd personally consider one of the easiest to play since his kit is very straight forward, simple to use, and allows room for mistakes
Vayne, Akali, Zed, Aurelion Sol and evelynn are all also champs that I definitely wouldn't consider "Intermediate"
I think a good way to list them would be to look at win rate by games played. Just take the biggest change as hard and smallest change as easy. With this criteria, the hardest 10 in order are

The easiest 10 in order are 
TY everybody
