Kobold Geomancer is an okay replacement.

Chromaggus can work for Vol’jin, but Vol’jin generally represents removal. So Big Game Hunter might actually be better in that spot. I would say Lightbomb is more important and versatile than Vol’jin. You will often see at least one Lightbomb in Control/Dragon Priest, but Vol’jin goes in and out of Priest decks.

Seems like a reasonable idea to try.

Second Violet Teacher.

Gormok or Void Terror for Brann. Darkbomb could work for Peddler.

Gormok or Void Terror.

You could try Kor’kron Elite as is used in Crane’s Patron Deck: http://www.hearthstonetopdecks.com/decks/crane333s-season-21-midrange-patron-warrior/

Yeah, I think Ragnaros would be a good option.

This deck is obsolete because of the Warsong Commander nerf. Try this one instead: http://www.hearthstonetopdecks.com/decks/midrange-patron-warrior-deck-list/

You can replace Grommash with a Sludge Belcher in the list I referenced.

I personally like Loatheb, but either choice is good.

Second Shade of Naxxramas.

Second Violet Teacher or a Tomb Pillager. Preparation is a pretty vital card in this deck.

No, it’s the first card on the class side? I might be not understanding what you mean.

You can get to legend, but this deck is probably as weak as it has ever been.

Sen’jin Shieldmasta or Sludge Belcher, but you’ll struggle against aggro without him.

Second Knife Juggler or Wolfrider. Yes, you can get legend with this deck.

Second Keeper of Uldaman? I’m not sure.

We’ll see, but you’ll be highly considered. I really appreciate your contributions to the site! If you have more thoughts you can e-mail me: evident[at]hearthstonetopdecks[dot]com

Darkbombs or Piloted Shredders.

Piloted Shredder, but Tomb Pillager is pretty important in this deck.
