Your Hero Power will remain 0 Mana.

Blackwing Technician or Faerie Dragon.

Yep.

I would wait and see how good it is, I’m not sure Freeze Mage is going to work in this meta.

You can try Sylvanas but the taunt is pretty important.

I’d run combo version that doesn’t use Jaraxxus: http://www.hearthstonetopdecks.com/decks/stancifkas-kazakus-renolock-mean-streets-of-gadgetzan/

I added a guide for this deck here: http://www.hearthstonetopdecks.com/decks/aggro-face-shaman-standard-wotog-deck-list-guide-season-26-may-2016/

I don’t mind the Thaurissan, but I’m not a big fan of Yogg. I’d rather play a second Feral Rage.

Second Feral Rage, although it’s weaker without Fandral.

Fluffy just got legend with it: https://twitter.com/Fluffy_HS/status/805534587392839681

I’d probably just run a second Healing Wave.

They would work, Alexstrasza is probably better.

Second Deckhand or Argent Horserider.

Yeah, I was going to say the cards you listed are kind of slow. This version of the deck seems pretty well optimized.

Maybe, you’ll be weaker to Midrange and better against control.

Yeah, this deck will probably need some help to beat all of the aggro out there right now. I still think this deck will be playable though.

Faster Midrange decks should beat this deck (Midrange Shaman, Tempo Warrior). It has a hard time dealing with early on curve threats.

Acidic Swamp Ooze.

Yeah, that seems fine.

I’d just go Acidic Swamp Ooze, you probably need weapon removal right now.
