Count Swain skin
There are so many possibilities for Swain skins. This is one concept I became fond of very quickly. His raven gets replaced by a bat which can shoot a crimson laser through Q. W can be a red ritual circle with different markings that impales enemies on stakes instead of of talons. E can be a dusky swarm of bats clinging to an enemy. Ult is obviously transforming into a giant bat-creature that sends out smaller vampire bats to drain health from them (a theme which fits bats more than ravens anyway).
Dude really needs more skins :(
