Ravaging Ghoul, but there’s no real replacement for them.

Tough to say, I’d try it without if you don’t have them yet (I wouldn’t craft them if you’re on a tight dust budget).
J4CKIECHAN'S (Standard) Midrange Hunter (May 2016, Season 26)
Sounds reasonable to me!

It’s strong and probably going to be around, but I’m not ready to call it a meta-defining deck.

Ragnaros could work, Sylvanas is already in the deck.
Prelude's MSI EGLX (Standard) Control Warrior
I would probably craft Ragnaros, that has felt like the most consistent legendary of the three. Nefarian or Ysera and BGH could replace the other two.

Replacing Solemn Vigil is pretty tough, I don’t have any great recommendations, but Loot Hoarder is an option. Corrupted Healbot isn’t in the deck anymore (I think you commented before I updated it).
Firebat's (Standard) Aggro Warlock Zoo - Season 26, May 2016
Harvest Golem and Forbidden Ritual.
Prelude's MSI EGLX (Standard) Control Warrior
Acidic Swamp Ooze, Nefarian or Arch-thief Rafaam, and Whirlwind.

Second Fan of Knives and Harvest Golem.
Amnesiac's (Standard) Midrange Shaman (May 2016)
I really haven’t seen any decks with Hallazeal in them, sorry!

I don’t think it’s essential, I’d try Cairne or The Black Knight if you have it. You could also try an Infested Tauren.
