Soulstealer/Grim Reaper Yasuo

Soulstealer or Grim Reaper Yasuo Concept I'm thinking his appearance would be a skeleton in a Grim Reaper cloak, he would use a scyth to attack and have a shadow isles/soul stealer theme. This skin would be an ultimate skin due to a new voiceover, different quotes sounding more undead and grim, and additional features... on to the ability particles

Passive: Yasuo's flow shield would be green particles(like Thresh's) and make ghostly sounds when appearing rather than win sounds, it would continue making sounds until the shield is over..

Q: Yasuo would lunge his scyth forward, after his 3rd lunge, he will be surrounded wit a bunch of souls that float around him(souls would look like a small thresh soul), he will turn into a ghostly form(like Karthus's death defied particles) and begin to levitate. he would also have ghostly green particles around him. His tornado will have those same ghastly green particles and have ghostly sound affects too, in this tornado would be a bunch of souls which whirl around.

W: Yasuo makes a wall of bones surrounded by green particles and souls flying out of it, when it is hit with a projectile it will make a bone crumbling or bone cracking sound. While the wall is there it also makes ghostly SFX

E: Yasuo dashes as normal, when combined with Q he whirls his scyth around

R: Yasuo dashes to someone who is airborne and holds them, while holding them with one hand he whirls around his scyth with the other, with it, a lot of souls whirl around, this makes ghostly sound effects. Afterwards, he slams the opponent into the ground, making a splash of mud and leaving a tombstone saying R.I.P.

Additional Features: -New interactions with shadow Isles champs. -When killing a minion or champion, it shows an animation of a soul flying out of them and into yasuo, he then gains a soul that flies around him in a circle, it doesn't benefit Yasuo in anyway, it's just for the effect, Yasuo can gain up to 20 souls, if yasuo has 1-5 stacks, he has 1 soul flying around him, 6-10 stacks, and he has 2 souls, 11-15, 3 souls, and 16-20, 4 souls. -When Dying, his robe fades away and he falls on the ground as a skeleton, breaking apart, he loses all his soul stacks, and the souls floating around him fly in different directions

That is all I can think of right now! Please leave feedback on any other ideas, or if it is a good idea, or just a horrible idea. Thank You!
