Have you considered Mulch or Kessig Cagebreakers?

Grisly Salvage is already there, and is way better than Mulch. Same cmc but Salvage is an instant, shows 5 cards instead of 4, and you have choice of creature OR land (or nothing, because of the "may" clause). Mulch is occasionally good for fueling Raven's Crime but 90% of the time Mulch is outclassed by other cards.

Kessig Cagebreakers is a bit too slow here. If anything, I'd put it in here as a 1-of.

needs red for faithless looting and you need to cut some of the crimes, in favor of Vengeful Pharaoh

I would throw some Rancor in there, simply for the fact that Tarmy get's ever so slightly bigger for having them in your graveyard, and you only really need one of them. Maybe Groundbreaker as well?

You're running ravens crime but no life from the loam. That's bad. You're only running 4 fetchs, with bloodghast and ravens crime...That is also bad

Looks good. +1.

benelas16 - I think Raven's Crime is here to put land in the graveyard because torridus doesn't want to run more fetches. I imagine "target player" discarding may often be torridus.

Vladimara makes a valid argument for including an enchantment, but Rancor doesn't strike me as a good idea because it's so darned sticky. Evolutionary Leap makes a little more sense as does Seal of Primordium, Quest for the Gravelord, and No Rest for the Wicked. Also, why not an artifact, too? Something like Nihil Spellbomb?

But I don't see this as a "mill" deck, not even a self-mill deck, and I would remove that from the Hubs.
