Yorick : Champion rework

I have a few thoughts on the yorick champion rework that i think might work pretty well. These ideas aim to create a melee brawler champion that also keeps the theme of necromancer/dark mage. I am still trying to figire out some numbers for the abilites but i think this will be fine for now.

Yorick Abilites:

passive:soul siphon Every third basic attack on an enemy champion restores 5% of yoricks maximum health and gives yorick half a lost soul yorick needs two half lost souls to make 1 stack of lost soul

Q: Reanimate, Yorick gains a stack of lost soul every 30 seconds yorick can hold up to 3 stacks of lost souls maximum. yorick can cast reanimate on either an ally unit including,Minions and champions or enemy units including,jungle monsters,minions,or champions. When casted yorick revives and takes control of the target unit if the unit is a minion or monster it will follow yorick and attack whatever yorick attacks. If the target is a champion yorick can take control of the reanimated champion and can cast any non-ultimate abilites. But these abilites only do half of their initiall damage and added damage.reanimated minions last 30-40 secons depending on yoricks lvl and reanimated champions last 10-15 sexonds depending on yoricks lvl. Useing reanimate on a champion uses 2 stacks of lost souls and useing reanimate on an minion cost 1.

W: rejuvinate, passive: yorick and his reanimated units gain 5% extra health regeneration and 5% extra movement speed

Active: When cast yorick spend 10% of his maximum health to gain 30% attack speed for him and his reanimated units.

E: Rusted shovel: Passive Yoricks reanimated units and himself apply a stack of rusted shovel to an enemy unit dealing 5% of the enemies maximum health per second. There can only be 2 stacks of rusted shovel aon an enemy unit at one time

R:Shallow grave: yorick summons a gravestone at a target position any champion can pick up this gravestone to gain the buff of shallow grave. Whichever champion has the shallow grave buff can not have their health pool fall below one for 2/3/4/4.5 seconds. But these same champions are susceptible to any type of health based damage and can still die meaning units can still die to stacks of yoricks rusted shovel.

I hope these abilites can either provide inspiration for the new yorick update or with further thinking and calculatioms can be balanced abilites sutisble for the yorick rework.sorry if my grammar is questionable i tried my hardest to make this understandable thank you for your time.
