I'm really torn on this champ so far...
So his passive is like the new Graves passive, which I like, but way more complicated with the other stuff added on. His Q is like Sivir's ricochet, the W is like Xerath's Q with some cc added in, and his E is like a combination of Caitlyn and Teemo's traps. Finally, his R is a combination of Irelia's, which I don't like, and Caitlyn's, which I do. Now there is another passive that was not added in but a rioter mentioned in the comments:
"The reveal is missing something that got locked in too late for localization.
Beauty in Death - Killing blows spawn a blooming flower on the corpse that reveals and slows enemies nearby before detonating for damage."

While his kit doesn't seem original, the combination is interesting, and I love the art style. I can't wait to play him when he comes out.
P.S. : Sander Cohen is still far more interesting
