Made some cuts and some adds, thoughts?
Maybe, if you have time, instead of just listing cards, tell me why you would cut them?
I'm sorry. I was in a hurry and thought I could explain later.
Here are my comments on the cuts.
Bonehoard: because
Lord of Extinction is better,
Mortivore would be an option too, but in my opinion it ain't that impactful to justify the slot.
Whip of Erebos: it's ability is similar to your general's, so it's not needed, besides it prevents from sac-recur tricks.
Altar's Reap: I don't like one-shot effects in EDH, they have to be really huge to be worth it.
Grisly Salvage:
Satyr Wayfinder is far better because you can recur it.
Wretched Confluence: not that impactful to me.
Champion of Stray Souls: too mana intensive and similar to Meren, another sac outlet like
Altar of Dementia will be far better.
Golgari Thug: I don't think this deck is meant to dump your library into your graveyard, so you don't need that many dredge cards, if you're looking for another way to fill the grave I recommend you
Deadbridge Chant.
Hermit Druid: you have a lot of basic lands, so you're not comboing out with this, but people will hate you all the same as soon as they see this card.
Phyrexian Gargantua: plain weak.
