[Champion Concept] Yorick's Long Lost Cousin (Need Your Help!)

Hey Everyone!

So I had some ideas for a new champion, realized it might work as Yorick's rework and started tuning it towards that before I found out his rework already seems well under way. His new kit seems pretty cool, so I don't want to propose this champion as an alternate Yorick, but I don't think I can deny that this kit could fit Yorick. What I want to do now is post my ideas, and ask for your help in creating more of an identity for this champion, maybe differentiate him from Yorick if he's too similar. Thanks!

Passive: Instead of mana, this champion would have a secondary resource bar based on their minion kills (perhaps champion kills and assists too). The bar starts out empty and increases as the champion gathers the bodies of fallen minions or champions. The bodies could even follow him around as a sort of zombie horde. I'm thinking each kill could add some resource and increase his maximum amount of this resource, with it very slowly regenerating over time. His basic abilities also scale with a percentage of his CS, as oppose to other stats, and I was also thinking that he doesn't gain attack damage per level, instead this also scales as some small percentage of his CS. I was also toying with the idea of the resource not regenerating, and being permanently used up with abilities, but this may be too punishing.

Basic Abilities: This is a part where I need a lot more help. Originally when I had this planned as a kit for Yorick, these abilities would consume his resource to summon ghouls with similar effects as his current kit, but this would make him too much like the current Yorick, which Riot is changing anyways. Since he's scaling with CS already, it looks like he would be building full tank or maybe a bit AD and be a tank/fighter champion, so his abilities probably should compliment this playstyle.

Ultimate: Here's the one part of his kit, besides his new resource mechanic, that I'm most excited about. This ability has zero cooldown, consumes all his resource, and gives a MASSIVE buff to all his stats (barring a few, like move speed and CDR) for ~10 seconds. After this, he dies. Kayle can't prevent this, and even Zilean can't bring him back. Every champion kill or assist he gets while his ultimate is active reduces his death timer by some amount (probably more for kills than assists). I was thinking too his kill bounty is reduced by half if his ult kills him, doubled if the enemy team kills him. This is to provide incentive for the enemy to fight him and maybe so he doesn't get as punished for randomly suiciding all the time. Also toying with the idea that his death from his ult causes some AOE damage (killing a champion with this doesn't count towards the death timer reduction). If an enemy kills him, he still explodes but does no damage (I just think it'd look funny)

And that's basically it. I was also thinking of giving him a unique item that could serve as his body collection vessel, since this passive already gives him stats with kills, and it might be too much to give him 6 slots to build full tank. I wanted his passive and ultimate to have a sort of dividing effect on his playstyle, so he's not too encouraged to just freeze lane and farm for 40 minutes, since his ultimate would be really good for teamfights and skirmishes. Since this was also originally a Yorick kit, the resource limitation early would make his early game less overbearing, while still giving him a great lategame presence. He is also probably one of the few champions that would benefit from the Revive summoner spell, as well as teleport (it would be really easy for him to rush down objectives this way, using his ult to burst down a turret or dragon then reviving and teleport back into lane, for example). Ghost would also be a good option so he's harder to kite.

Skin Ideas:

Angry Pinata: Collects candy from each kill. Bonus gold when you kill him during ult makes him like a Pinata.

Zombie Olimar: If the bodies follow him around when he collects them, he's a lot like Olimar from Pikmin.

Let me know what you guys think! I was laughing my off when I came up with his ult XD.
