I think maybe you should try Yahenni's Expertise as a way to do some early wiping and cast something for free, might also try Pestilence, Attrition, or Whip of Erebos in the enchantment slots. On the more costly side, Yawgmoth's Will would be really sweet.

Yahenni's Expertise, Yawgmoth's Will, and Whip of Erebos Would fit in this deck only problem I don't know what to remove. Pestilence would be hilarious with Exquisite Blood. I'll test it out

Looks a good deck, but if you are looking for more Sac Outlets, I feel Bontu the Glorified is a good option to include.

I'll check out bontu and see what I can come up with

Victim of Night and Ashes to Ashes. Sure, the former is specific and the latter is painful, but unless your meta is filled with token players, Bile Blight is really bad in EDH. Hour of Glory only works once and if their God deck is voltron, some players will just not care you got rid of their commander.

Hour of Glory is vastly preferable over Ashes to Ashes - it doesn't require you to pay 5 life, is an instant, is reusable from the graveyard, and doesn't require two targets to fire off.

Bile Blight is at its best against tokens, but even in games where no token creation happens, there are an awful lot of relevant creatures with less than four toughness.

Have you play tested it?(IRL)

Yep so far the results were I got 3 hatred kills. Swung with a army of dinosaurs against a Gishath, Killed everyone with double Torment of Hailfire using Mirari. And almost milled out a Oloro. It does have a hard time dealing with some control decks since it's a arms race on getting the right instant to kill them with. But overall The deck have proven to be a threat when it goes off or provoked.
