Great card in the right circumstances, but I don't think the deck is there to support this card. I hope one day it will be and then this card will be in there. Don't think the Murloc tag is worth much. The synergy has to come from its battlecry.
Most of the time I expect this to be no more than just a 3 mana 2/3 with deathrattle: draw a card. Not necessarily bad, but I wouldn't run it over a Loot Hoarder. Sure, you can run this in a Drakkari Enchanter deck or hide this behind a taunt, but I don't think that'll ever surpass meme tier.
My gut says this is a high roll card. Seems hard to balance enough ramp and big spells to make this a worth while risk that you don't draw the big stuff and whiff.
Yes the mode offers more and better decision making and is overall an improvement in comparison to the lab of legends however I don't think that gp is thaat hard to beat.
If you use all the options offered by the campain you will fight him with a godtier deck almost all of the times and with such you will stomp him.
However: 1 tipp for beating gp: make sure his board is full when you hit him below 20 hp to make the ship not spawn.
I'm not sure if a Fel Demon Hunter deck has enough support to see play when this expansion releases, but once it does this card will be in there and is there to stay. Crazy powerful card in the right deck.
Oh, here's the draw (get it) for minion based token decks. Though they, sadly, have to die to draw, so if you can kill them, you trade, draw, refill, try again next turn.
Mediocre card on its own and in order to be good it needs the support of other mediocre cards like Pounce. I hope it works out in a Lost in the Park deck, but I certainly have my doubts.
Upgraded Eye Beam with worse mana cost. I guess it is useful combined with Jace Darkweaver, but it will not even give you the outcast value of this card.
More boring Handlock support which the archetype does not even need. There are plenty of better alternatives out there already, especially in Wild. The fact it has the Demon tribe tag means it will see some play when discovered or via some RNG effect.

This seems very good to me. Refill for an aggro token decks. Plays nice with the squirls or glow fly.
Oracle of Elune
If there is enough card draw this and the taunt mana discount card could be combined for a interesting new style of token deck.

A decent card. That isn't good enough to see play these days.

New Demon Hunter Minion - Stubborn Merchant
Seems pretty good in DRDH.
New Neutral Minion - Enthusiastic Banker
3 stars for interesting... It's interesting.
New Warlock Minion - Anetheron
I've never played handlock, so I don't know how to say if this is good or not, but warlocks seem to think they can use this guy, so have at it.
Irebound Brute
I think this card is great as long as skull of guldan is around.

Sigil of Alacrity
I think this card is fine in a deck that has 28 really good cards and just wants to take up that last few cards with this.

Chaos Leech
I agree with Sykomyke but would just extend the idea of playing eye beam over this in almost all situations.
New Demon Hunter Spell - Chaos Leech
For a game that was supposed to be moving back to 'the board and minions matter,' there is a lot of spell based removal.
New Warlock Spell - Demonic Assault
It seems awkward at first glance, especially the 4 mana, but this does a lot for a lot of warlock decks: survival, burst, removal. Pretty good.

New Warlock Spell - Touch of the Nathrezim
Nice additional card for Tamsin Roame to copy.
New Warlock Spell - Demonic Assault
Probably worth it in Standard, not in Wild though because it worsens the Demon pool for Bloodreaver Gul'dan.
New Warlock Minion - Shady Bartender
Slots into Demon Zoolock. We might see the return of this archetype in Standard enabled by this card.

Should only be viable in Token Druid, but that archetype wants to stay on board and not draw cards instead. Confusing card to say the least.

Support card for the Druid Quest, but new Quests are bad, so this card suffers from that.
