Potential Mordekaiser remake

Heres my thoughts on possible mechanics that might make sense in a future mordekaiser rework.

Passive. Ironman Mordekasier gains a shield that scales off of level based on a percentage of his damage dealt. the new part of this passive is that when mordekaisers shield decays 5,10,15 percent of the decayed amount gets converted back into health. (this will help give him sustain now that spell vamp is gone).

Q. Mace of spades. if the target is alone it deals a large amount of damage. if the target has allies nearby then mordekaiser swings his mace in a large arc in front of him dealing damage.

W. Creeping death/Harvester of sorrow. Mordekaiser summons an aura of dark magic and steel shards around himself dealing exponentially more damage the closer the target gets. this spell will introduce a new sliding mechanic that causes mordekaiser to pull all enemies in the aura towards him. the pull does not interrupt or prevent spells or movement but every 2 seconds the aura will pull champions towards mordekaiser a distance of 25 units. (or whatever ends up being fair 25 might be a bit much but its a good visual). the point of this new spell is to help mordekaiser catch people without giving him hard cc since that is an integral part of his identity. the aura will also have a radius similar to anivia's ult. also the outer reaches would do next to no damage but if you got into melee range it would start to sting.

E. Siphon of destruction Mordekaiser launches a wave of destructive magic in a cone in front of him dealing moderate damage. (same as pre-rework)

R. Children of the Grave Same as pre-rework. also no more stupid dragon gimmick since with the mace changes he can have some wave clear again and can push on his own.

Obviously these numbers aren't exact since it was just to throw some ideas out.

Also feel free to comment other potential ideas for a possible mordekaiser rework.
