This card is insane. Especially in paladin, but every other class checks two out of three boxes. For playable neutral divine shield there's only -so far - [Hearthstone Card (Taelon Fordring) Not Found], Al'Akir the Windlord, Darkmoon Dirigible, maybe Argent Squire.

A great anti aggro card. With this and the soul package, warlock will become better than priest at shutting down aggro.

Okay, way to squishy to survive long, but this set every single class gets a buff! Which also buffs health - else the mounts couldn't appear later on - so if you run any such mount card, this pairs really well with it, and you can feasibly play it turn 1 for an extra draw, or even turn two if you're feeling lucky.

I wonder if their yet enough shopkeepers with Rise of Shadows and Sturmwind to make a market deck?

It's  a good tech card, but it's a toss up whether this will replace Gluttonous Ooze. Beast Tag doesn't help much in utility. I feel like Gluttonous Ooze is a more exiting card, being able to stabilise you, which can save you the game. This card is just good and reliable, which sometimes doesn't beat exiciting

I really like the control support, just feel that such a vendor should be tradeable.

It's good enough for combo and miracle, maybe even for Lock and Load Hunter?

Is there an official explanation for what this card does? 

I really like that this doesn't really support aggro

Too expensive for the cost, would trade it away all the time. 

There is so much more draw these last two expansions, this will often hit handsizes of 7+ cards. 

There's this obnoxious wild deck. Could become even worse. 

I want to like it, but I see no deck for it as of yet.

Great stats for the cost - with the spell focused cards of Forged in the Barrens and it's miniset it fits right in. Taunt makes it playable.

It's to much work - as of now. Maybe with some self-copying minions, a more efficient hand refill than First Day of School, and with lots and lots of optimizing this could become barely playable?

The name is really fitting for a tradeable card, I wonder how many others will explicitly mention commerce.

Looks like a wild card. There is more than enough spell generation there, and plenty of great spells of each relevant school:

Fire: Flame Ward, Fireball, Combustion

Arcane: Incanter's Flow, Counterspell, Ancient Mysteries, Conjure Mana Biscuit

Frost: Ice Block, Frostbolt, Ray of Frost

While fire could prove to be a problem, there are just enough great spells in wild, that any deck that likes to play fast and a lot of spells (Flamewalker Mage) could probably run this.

Also pairs quite will with Trueaim Crescent, and big minions that you want to have attack as often as possible: Moonfang, Lake Thresher,Teacher's Pet, Trampling Rhino. I could imagine a midrange deck with some cheap spells, and a Guardian Animals + Ramming Mount package.

As there are only very few arcane druid spells but a lot of them can be used in combo and meme decks.  So this card should help with some early survival.

Finally! I quite like arena, but I'm not good enough to actually justify spending gold there.
