A better Necromancer Archetype.

We all know Yorick is riot trying to see how well a necromancer would work in game, and honestly, making him an AD Bruiser was a bad Idea, I mean, He dose kind of just Q towers to death without any repercussions, and can 1v1 most people by pressing Q and E, Not very necromancer-y if you think about it. So, Here is a (In my Opinion) more.... "realistic"? take on a necromancer.

Passive; Ancient Magics. Champion gains permanent AP(1? maybe 0.5) and Mana(5 maybe) for every spell cast.

Q; Summon thrall.(low cooldown, high mana cost) Champion summons a Undead thrall(Just a Melee minion in black robes) under him. Undead thralls will join into the nearest minion wave, and have identical stats to minions. Undead thralls will change targets based on who Champion is targeting. If Champion is not targeting anything, they will behave as normal minions. Enemy champions, minions, monsters, and towers killed by Undead thralls count as kills by Champion. A maximum of 10 Undead thralls can be alive at a time. If Champion dies, Undead thralls will lose Health Rapidly.

W; Decay thy Flesh.(low cooldown, moderate mana cost) Champion casts a orb of dark magics to a location, the orb stops on first target hit and applies a stack of Decay. Targets who are Decaying take (number of minions Champion killed) + 10%/30%/50%/80%/120% AP as magic damage over 3 seconds.

E; Twisted Deconstruction.(high cooldown, low mana cost) Champion shields target enemy for 50/80/120/200/300, The shield lasts for 20 seconds. Once the Shield is broken the target enemy takes 120/140/200/320/450 Physical Damage, slowed by 30%, and a stack of Decay is applied.

R; Soul Revival.(very high cooldown, very high mana cost) Champion casts Soul Revival on all allied champions. Soul Revival lasts for 20 seconds, If a allied champion dies while Soul Revival is active, they are "revived" for 20 seconds with 10%/20%/30%/ health, and apply a stack decay to their killer, Once the 20 Seconds is over they die.

I'm Sure this is unbalanced as fuck, The numbers are more place holders than anything.
