Another great aspect of this deck is that by sticking to three colors you're able to play a bunch of Shambling Vents
Sacrifices for these colors are great ways of starting triggers like Blood Artist and more instants/sorceries wil care about Guttersnipes, and each are cool ways to build your Grixis deck in Commander
Im sure Im missing something that puts it all together as an engine, but for now Im satisfied binning my extra Champion of Dusk cards or Adanto, the First Fort tokens to close out a game
I don't think there's much else to say about this card, it does exactly what it says
Firstly, and most importantly, it doesnt actually ask you to sacrifice the creature you want to use it with
Overwhelming Splendor shuts down all activated abilities of other cards that the player controls, and they cannot activate loyalty abilities of their planeswalkers either
