On the topic of changing color schemes after VGU's
I really hope Mordekaiser isn't going to become your standard blue/green misty ghost after his VGU. He is an ancient revenant, the source of his power something far more vile and unholy than the black mist.
It may empower him but Mordekaiser's true power comes over his own dark necromantic arts, drawing from his own malice and will to dominate in order to sustain his immortality and never-ending conquest. He's got these cold Greyish, red hues in his abilities that I feel work really well with an Immortal Revenant King clad in heavy metal armor.

Or maybe we could amp up the darkness component due to him being described to have a blackened soul and eyes of pure Witchfire and make his abilities BLACK and fiery Crimson.
I dunno, just rambling at this point because I'm so hyped over Galio's VGU. Might just try formulate some thoughts on Morde's VGU once I've calmed down.
