A Janitor Yorick Skin.
I would give an actual picture, but I'm not a very good artist.
How about a Yorick skin where he's a janitor and instead of a shovel, he whacks people with a broom/mop?
His Mist Walkers could be little dust-mites and their graves could be specks of dirt/debris. His Q would be similar to now maybe with some particle effects. His wall would be like the edges of a mop bucket. His E would be him sweeping dirt/mud into people. The Maiden could be a cloud of dust or something that spawns his little dust-mites.
Yorick hasn't gotten a skin in literal years, so I figured he deserved some love.
Thoughts?
