Want to know an idea of a champ fun to play as, with, and against?

A champion who thrives on making enemies guess and allies hope they dont guess right. What do I mean by that?

An example would be like the cup game where you hide an object under one cup then move the cups around and have a person guess which cup is the correct cup.

How would this be implemented in league of legends?

Gambler summons 1 box and dissapears into it. The box then splits into 3 pieces and only the team of the gambler know which box he is in. The boxes and gambler stay stationary until an enemy picks or after 10 seconds. If the enemy picks the wrong box then they lose the game and the gambler steals some health, movespeed, and stuns them for 1.5 seconds.

If they pick the right box then the gambler is revealed and is slowed by 20% trying to make his quick escape. Move is unusable without an enemy champ to target. If no boxes are picked or the enemy runs out of range of the game they take double the penalty as if they lost.

Enemy champ and gambler cannot be targetted while in the circle zone of the game or damaged.
