Threw these together:

Reno Tempo

1x Arcane Anomaly
1x Mana Wyrm
1x Mirror Image
1x Arcane Missiles
1x Arcane Blast
1x Babbling Book
1x Sorcerer's Apprentice
1x Cult Sorcerer
1x Frostbolt
1x Huge Toad
1x Faerie Dragon
1x Flamewalker
1x Mirror Image
1x Forgotten Torch
1x Argent Horserider
1x Arcane Intellect
1x Water Elemental
1x Fireball
1x Kazakus
1x Polymorph
1x Ethereal Conjurer
1x Cabalist's Tome
1x Azure Drake
1x Reno Jackson
1x Faceless Summoner
1x Emperor Thaurissan
1x Inkmaster Solia
1x Flamestrike
1x Firelands Portal

Kazakus is absurd and Inkmaster into Flamestrike, Firelands, Tome or even Polymorph or Fireball something huge is also absurd. Lost a couple of games though and it kinda feels clunky and not very well-oiled.

I'm glad to see that they kept the WotOG tradition of giving away free packs through quests. Each faction asks to win 3 games with any of its classes: first the Grimy Goons, then the Jade Lotus, then the Kabal. Each quest awards 2 packs, so I guess we get 6 in total this time (I don't know if there are more quests after the faction ones).

The Tavern Brawl can be used to get them done: I have the worst luck with the current one, but with a bit of patience I completed the first quest already.

I've opened 45 so far and gotten a Finja.

I opened about 60 packs and got grenzo, mayor and kruz. Never buy packs. Never eat raspberries.

I opened 138 packs after pre-order and gold. And then the bug happened and I got to open 48 more....for freeeeee.

I don't know how to make a decent Jade Shaman deck.

I was able to make a more grindy Priest deck in Arena, so I'm looking forward to bringing that deck back, maybe modifying resurrect Priest? I am really liking the Kabal common, the potion lady.

Everyone is hyped up for Dragon Priest but I am happy that Control Priest is now somewhat viable again:

2x Mistress of Mixtures
2x Museum Curator
2x Dirty Rat
2x Shadow Word: Pain
2x Kabal Talonpriest
1x Shadow Word: Death
1x Thoughtsteal
2x Priest of the Feast
2x Shifting Shade
2x Greater Healing Potion
2x Excavated Evil
2x Corrupted Healbot
2x Dragonfire Potion
2x Entomb
1x Justicar Trueheart
1x Sylvanas Windrunner
1x Cairne Bloodhof
1x N'Zoth the Corruptor

At first I was concerned about the Jade Druid deck people are making, because Jade Idol gives it scary inevitability and makes it so you have to finish them off first. Thankfully they durdle enough in the early game that you can pressure them with Mistress, Talonpriest and Shade and then just N'Zoth them into oblivion.

Dirty Rat'ing something before you cast Dragonfire Potion or Excavated Evil feels really great, especially if the pick has a battlecry or a choose one effect. Once I got Darnassus Aspirant out with it. That card really isn't a 2-drop, though.

Greater Healing Potion is my pick for underrated card of the set. It lets you survive a ton of punishment so you can get a lot of value from your sweepers.

All in all I am just loving the new Kabal cards. It just so happened that Priest, Mage and Warlock are 3 of my 4 favorite classes (the fourth one being Warrior). Next up I am going to try some Renolock.

Red Mana Wyrm and Conceal are BFFs, holy **** that card can dish out some serious punishment.

Going to skip all things I don't care about (cards I don't see being good at all any time soon).

-------

Jade Idol is only going to be good if Jade decks are good. At least for quite a long time. There isn't a "best" druid deck that wants to go to fatigue often enough to make it good outside of a jade druid.

Mark of the Lotus is really good in wild but in standard it's meh. It's most of the combos you want from the 2 drop equivalent but a mana cheaper (and thus often a turn earlier). I think 2x Mark of the Lotus and 1x Power of the Wild might become a thing instead of just 2x jPower of the Wild.

The jade cards are basically going to be viable in standard if jade decks become one of the best druid decks. I honestly have no idea. It depends how fast the meta ends up.

Kun the Forgotten King absolutely wrecks in multiple matchups. I think it might be the best card Druid got for standard.

--------

Alleycat is just going to get run. It's not spectacular but it's still going to be a 2 of.

Smuggler's Crate is one of those things where in standard I don't think hunters have enough good turn 1 plays and it reads "crazy turn 2" so it might see play.

Trogg Beastrager, Rat Pack, and Knuckles are all going to see play if that deck becomes a thing. I'm not sure on any of them yet, but I think the beastrager will probably just be a 2 drop b/c they don't have anything else and that might push it a bit.

I think Dispatch Kodo is the best card Hunters got.

--------

Kabal Lackey makes it possible to go turn 1 secret turn 2 valet. It also makes turn 10 Alex + Ice Block possible. I have a feeling it will see some play.

Volcanic Potion will at least see play in Reno.

Kabal Crystal Runner has a high chance of seeing play AT SOME POINT. They are going to keep pushing this deck until it's a thing. If not this expansion then probably once flamewanker rotates out.

Greater Arcane Missiles is insane turn 7 on an empty board as an aggro deck. I feel like it's going to be good.

Solia will see play if Kazakus sees play. Kazakus's 10 mana spell feels like the main payoff for playing this.

---------

Getaway Kodo is really really good but I don't know if it has support.

Small-Time Recruits is going to eventually able something stupid.

---------

Like for Priest..... Mana Geode is bad. Definitely the shaman of this expac. Mown should be happy.... er.

--------

Counterfeit Coin is probably the best card of the set. They printed Lotus Petal but it's a spell in the spell synergy deck.

I don't know if the jade decks will be a thing. My inclination is maybe until the rotation and then know.

Lotus Assassin seems really really good.

-------

I don't know if jade decks will be a thing. For shaman my high inclination is no. Not at all. The cards don't seem like they make sense for shamans.

Finders Keepers may be insane in standard. In Wild it's not going to be.

Jinyu Waterspeaker and White Eyes seem like insane Control Shammy cards, but I don't know if that will be a deck.

-------

For Warlocks I think the potions, abyssal enforcer, and the 6/6 that adds demon to hand eot are all "solid" but I don't know if that's enough.

------

Hobart, Pawnbroker, and Gadgeteer seem insane on curve but really bad topdecks.

Sleep with Fishes seems like it might work. I think control warrior will play at least one.

Alley Armorsmith seems good unless priests are top class.

-------

For neutrals I like:
Mistress of Mixtures
Patches
Dirt Rat
maybe Grimstreet Smuggler
maybe Kabal Courier
Sergeant Sally
maybe the jade golem cards
maybe Kazakus - this one seems massively random to me. It seems insane but the question will be "Is it the right kind of insane for the situation often enough?"
Doppelgangster will definitely work if the buff decks work.
And I like Wrathion

----------------------------

And thus is my informed uninformed opinion on set. Feel free to call me idiot now.

I was wrong. Red Mana Wyrm might become a thing in rogue. Like.... I don't know if it will but it's definitely scary enough to have a chance. I'm having trouble deciding if the old-fashioned Leeroy kind of list is better though.

It's nuts.

For now, I'm playing Pirate Warrior. So many people out there trying out super-greedy new stuff and opening themselves wide for a turn 5 lethal.

You may have overlooked Drakonid Operative and Dragonfire Potion during your first glance, but it's OK. You'll be seeing a lot more of them in the months to come.

I think his statement was "Everything but Mana Geode is good."
I'm not really all that happy, since I'm not terribly fond of dragon priest, or the added variance of reno builds. I'll have to see if I can make some control decks with the new cards eventually though.
also jade golems are kind of cancer to try and out-control without something like nzoth.

I thought Mana Geode was the card I'd been looking for, but its just bad. They need this effect on a minion with some punch for the effect to be any good.

Pirate Warrior is disgusting. I gained 5 ranks in about 20 mins. I think it will level out once people get sick of playing Jade.

Jade Shaman is fun. I like it more than Jade Druid, but I think that's a play style thing.

White Eyes is very strong, or has been for me. I haven't play against it yet.

Whats your pirate warrior list? Mine wasnt working very well.

I have been losing to Hunter Rush, and if the highlander decks can get a Reno off, you might as well concede.
Also, I have found Frothing Berserker to be a dead card a lot of the time. I almost always want to cast something else in my hand instead. Been thinking about replacing them with the Corsairs.

Bleh 3 legends i dont own.

I think Jade decks are going to go away.

It's like C'thun druid. Everyone is playing the **** out of it in the first week or two because it's the obvious pushed deck build everyone really wants to try, but I don't see how it sticks around long term. It's too slow against aggro AND I think 3 other Druid decks are just flat out better as well.

The druid cards I still really like are their new legendary and Mark of the Lotus. Both are a lot stronger than I originally gave them credit for.

-------------

White Eyes feels really strong in shaman, but I'm starting to feel like the rest of their new cards are just crap. I think they are going to go back to playing a slightly altered midrange or aggro variant of what they were playing in Whispers meta.

-------------

I think Rogue will end up playing Miracle. The question is what will the win condition be? I've tried everything from double shadowstep with leeroy to red mana wyrm to whatever and it's going to take someone smarter than me to finalize whatever the list is going to be.

-------------

I think Control Warrior is going to play their new taunt and pirate warrior will be a thing for at least another month. Patches is insane.

-------------

Like... I have no opinion on the other 5 classes b/c everyone is either playing a bad jade deck, a miracle rogue, a pirate rogue, or a pirate warrior. I think they make up like 10% of my opponents in my games this expac total COMBINED.

Miracle Rogue got a huge boost with Counterfeit coin and Red Mana Wyrm.

I agree Jade decks are going to fall away. They needed to include like, 1 more neutral minion with the Jade effect to make it a little more consistent.
