Idea For A Champ New Weapon Type

Seen I started playing league back in season 1 on my first account i always wanted to see a champ with a ring blade , I think riot could make this concept work well on the right type of champ be maybe top,mid,jungle type assassin that benefits off roaming a lot have it do like a draven ult but instead pulls them into a combo u can get off , i dont truely know but i think its a great weapon type and would be a great concept for this game
