Zed skin's are few as many others, and an idea i have had for a long time is Shadow Zed, in which you play as the shadow that zed casts. When he casts a shadow, instead of another shadow appearing, he calls forth the original zed.
It'll be broken because the enemy will be too confused to retaliate
To get around the idea that he would be broken as the shadows would be hard to discern, make the shadow zed black, while all the other 
s are white smoke. Once people see the first white smoke fakes, they will know what to do during fights.
