Gravepurger (EDH / Commander)

This deck aims to win through one of the 3 Gravepurge esque cards in combination with our commander. The deck wants to play out as many of its self mill/draw creatures to fill up our graveyard, and then cast a Gravepurge while Syr Konrad is on the battlefield. This will hopefully chunk our opponents down until we win with a Gray Merchant or a beatdown win. This deck uses a lot of commons that don't get much love, which might hinder the decks consistency, but I was determined to make this deck with as little noncreature cards as possible, so I had to improvise a little. The only other noncreature/nonland card in the deck is Altar of Dementia, which I think works so well in this deck that it's worth the slot.
It's also worth noting that winning through commander damage is possible, as Nighthowler can pump our commander to an arbitrary size
I've also considered switching out Pestilence Demon for Vilis, Broker of Blood. Pestilence Demon easily keeps the board in check if it sticks, but Vilis does that as well, albeit targeted removal rather than mass removal, and also provides a lot of extra draw. Or I could go with a less mana intensive Erebos, Bleak-Hearted that also provides both of the things I've previously mentioned.
