They are very similar decks, this version is more aggressive, while the one you linked is more traditionally midrange. It just depends on your preference really, I made a guide for this one because I think it’s far more popular at the moment.

Yep, they’ve done this one previously.

A tech card is generally something that is used against something that’s popular in the meta. So right now Doomsayer and Shaman are popular, so Crazed Alchemist can remove Doomsayer and 0-Attack totems. Harrison Jones is another tech card that’s used when weapon decks are popular (like right now).

Nefarian might work for you.

I don’t mind Gorehowl, I just think Malkorok is better. Arathi is a viable option.

I guess just go second Thunder Bluff Valiant, but the Onyxia seems pretty important with the Evolve.

Second Carrion Grub and Flame Juggler.

That’s fine, Ooze is in as a cheaper option that allows you to play a threat along with it (or heal).

Harvest Golem and second Flame Juggler.

River Crocolisk or Flame Juggler.

I’d say it would be pretty difficult to play it without her.

Gorehowl isn’t bad, but the heart of this deck is tempo and Malkorok gets you a weapon and a minion. This deck is also pretty aggressive, so often you’ll want to go face with the weapon where that isn’t a great option with Gorehowl.

You could remove the Keeper of Uldaman.

That’s fine, you could also double up the Feral Spirit.

It’s a viable option, I just found that Sjow’s version with Rafaam might be better.

You could swap it for Stranglethorn Tiger, but the Tiger is usually guaranteed to stick to the board.

I’d maybe just try Knife Juggler. No, Divine Favor is very strong in Paladin Aggro decks.

It should work fine, I would personally use this list: http://www.hearthstonetopdecks.com/decks/midrange-shaman-decklist-guide-standard-may-2016-season-26/

No, I recommend this deck if you want to play Midrange Shaman. If you want the al’akir version you can try this: http://www.hearthstonetopdecks.com/decks/devous-midrange-shaman-hearthstone-eu-spring-prelims-2016/

Because it’s a top deck, Sjow got #1 Legend on NA and EU with it.
