Loatheb or Sylvanas.

Loatheb.

No, it’s a token.

Second Unstable Ghoul, but replacing Grommash makes this deck pretty tough to play.

Loatheb.

Second Unstable Ghoul, but you are really killing your win conditions by not having him.

You will still get them regardless, I believe you receive them when you unlock the first wing.

No, they removed the preorder anyway.

No.

No problem, Happy Diwali!

That works as a temporary fix, obviously Dr. Boom is very nice to have.

I’d rather have Nefarian or Chromaggus than Alex, but a big Dragon is what you need.

Two Argent Squire and Knife Juggler could work.

I don’t think he’s that good in this deck, but you could take out Ancient of War if you wanted to add him.

Acolyte of Pain, Fiery War Axe, and Death’s Bite are the main cards you want. If you think it’s aggro, Unstable Ghoul and Armorsmith are good keeps as well.

1. It’s generally not worth it, the silence would be better targeting a taunt minion to get in damage.
2. I don’t think any of the cards will see play in the decks.
3. Midrange Hunter, Midrange Paladin, Dragon Priest, and Zoo.
4. Tempo Mage, Aggro Druid, and Dragon Priest.
5. I would stick with Midrange Druid if you don’t have Fel Reavers.

Second Shade of Naxxramas.

That’s true, but you control when you play it. It’s good against Mysterious Challenger and Dr. Boom.

Justicar can be played in other decks like Midrange Paladin and Control Priest. Baron Geddon is only really used in Control Warrior, so i would go with Justicar due to versatility.
