Idea Dump: Skin and Champion ideas

I thought I'd share some thoughts about some skins and champions. If someone(or Riot)wants to take some and run with them, cool. Some ideas have already been discussed on other posts and I'll iterate some for awareness sake. Here goes...

PROJECT: (This has been shared already, but I like this concept)

Skin line for just Voidborn: What the Battlecast line almost did, then we got Mecha and Eternum . Wouldn't it be cool if we had a skin line just for the Void monsters? Like Cosmic Terror or something to that effect?

Speaking of Eternum, I thought about something like Eternum after seeing Falconshield's video Arcane Shift, having a different perspective on Ezreal's character.

Now a Champion concept: A Support/Assassin. I thought about this after learning about 's first mate, I forgot his name. But I thought maybe what a Support/Assassin would look like is a stealth/vision based kit, having an ability that puts "wards" out that when found by an enemy champion, explodes and deals damage to them. Also had the idea that this champ wouldn't deal too much damage unless attacking in unison with an ally, kind of like w passive. Got nothing as far as mechanics or specific designs, but maybe this'll inspire some discussion?

And that's what I got. Hope this was entertaining at the very least.
