Champion Concept: Marcin,The Clockwork Mime

Hello everybody,this is the first time im posting here(i have been playing since season 1 though)so bare with me!

this is a champion concept i came up with and i would any kind of feedback you can give me.Im not good at drawing so no images just his kit.Imagine him as a mechanised-clockwork mime(orianna type of mechanised),with a mechanical umbrella in hand!

Marcin is designed as a utility based support(could also be played as jungler i guess).His greatest disadvantages is that 1)he lacks a true ultimate skill,2)he doesnt do much damage apart from the active of his Q skill.

His greatest advantage is tons of crowd control abilities if paired with the correct champion,meaning he is much stronger when he has a crowd control heavy team built around him.

His abilities kinda resemble the whole mime show theme,so here goes.

**Passive ability: Check your ticket! **

Marcin steals 'x' amount of gold from any opposing champion that walks within an area around him.Marcin cannot steal from the same opponent until 'y' amount of minutes have passed.

Q: Mechanised umbrella

Passive: Marcin has increased autoattack range while he is holding his mechanised umbrella,and also blocks a portion of the damage he receives from autoattacks.

Active: Marcin can throw his umbrella at target location, slowing and damaging all enemies caught in the area, losing the passive effects in the process. Marcin can pickup his umbrella from where it landed to gain the range increase back. opponents can step on it to destroy it. If Marcin doesnt pickup his umbrella,or it gets destroyed by an opponent, then he creates a new one after some time.

**W: Invisible Glass trick **

Marcin can setup invisible pieces of glass throughout the field using the most famous mime trick ,which he can later activate. An activated glass will become visible, and will bounce back the first enemy spell projectile that hits it. Enemies can break the glasses accidentally by walking through them, which will apply a small slow to them.(will probably need to have a limit on how many glasses you can have at once).

E: its showtime!

Marcin after a small delay,puts on a show. any enemy champions caught in the range of the spell get dazzled for 'x' amount of seconds by his performance, not being able to autoattack, use spells, or move (probably small duration, like 1 second).

R: Mimicry

Marcin mimics an allied champion for 'x' amount of seconds, taking his form, and copying his basic abilities(not the passive or the ultimate). Marcin can use the copied abilities only once each, for half the stats of the original ability. Marcins mimicry ends,either when the duration ends,when he activates ultimate again,or when he has used all 3 of the copied abilities.

Ability details

Passive and Q are pretty self-explanatory.His W second effect can be used in many ways.Disengage,harassing (imagine bouncing back an ashe arrow and turning around a fight like that,or bouncing back an ezreal q harassing him in the process,pretty much a yasuo wall,stronger,yet with a cast time instead of instant).

E will stay active for more than a second(maybe 3).any enemies caught or walking in the range will get dazzled for 1 second.any autoattacks or spells targeted to marcin,will instead turn into vegetables that will drop on the stage,and wont harm him.

There is a gazilion of ways to use the ultimate.Mind tricks(especially when used on fellow jungler),double cc with soooo many champions,double shields etc.although the copied abilities only get half the damaging or healing or shielding stats.(full duration of cc though).

So what do you think guys??Too op??interesting or boring?thnx for any feedback.
