Sooooo i have this idea

So basically its a champion regarding the 4 horsemen; famine, war, death, pestilence. Basically there could be a champion that harnesses the powers of all 4 of the riders. There are 4 of them, and 4 ability slots so it is perfect. I was thinking on this, and you could have like his Q be War, where he gets an attack boost and maybe attack speed boost, his W be Famine, and it could be like an ability that slows his opponent, E be pestilence, and its a damage over time type of thing. His alt would be Death, and it could be like he turns into death, and all the damage he takes in over a certain period of time he then dishes out, and if he kills the target then he gains a buff for a certain amount of time( you know because absorbing the soul because he's the angel of death). But this is just an idea, I mean you can make his E death, which is a scythe that pulls you in and have one of the other horsemen as the ult. I just really like this idea because you can do so much with it, so if you guys have any ideas for this feel free to comment them! Also Riot if you see this.... you gotta admit its pretty good x)
