New champion concept(shadow isle)

Ok so i came up with this crazy idea for a champion that id like to see just because it isnt like other champs :). Ok for the story i was thinking a soul that escaped the shadow isles and seeking revenge (I THOT OF THIS BEFORE KALISTA CAME OUT :/ ) but could change it to a corupted soul that was once good but sum1 from the isles changed it. For his passive: He can not basic atack but instead he passes throo units so that means that his atack speed will actually be his movement speed + your skils with the mouse ;). For his spels: i was thinking like for Q: whenever he passes throo an ally or foe he can make a soul thread that lasts xx seconds and upon second activation he can dash to that target if ally he gives some movement speed if enemy he deals some true dmg and aplies a slow (he always goes on the other side of the champs). For his W: he gains imense movement speed and the ability to pass throo wals for xx seconds if he hits an enemy he knoks them upward.For his E: im not really sure what to give him here (id like to se something mixin with his q threads :/) just because he already has enough movement so you guys could try to fill that for me. AND NOW FOR THE ULT !!! R: He needs to be bound to atleast 1 champ in the game to do so he starts spining with all the champions he is tied with dealing dmg (the more champs the more dmg also none of them can cast spels or move or be targeted for xx seconds). You know those games when u just have that renekton or maokai that your team cant ignore cause they havto peel for the carry? Well this ult will be perfect it would disable the tanks for the short period of time and deal dmg in a wide range or you could just take their carries and run with em :) well thats it i know its kinda stupid but id like to se more diversity in the game kinda :/
