Best guess:

Tier 1: Egg Warrior, Tempo Demon Hunter, Umo Malygos Druid, Highlander Hunter

Tier 2: Control Priest, Quest and/or Control Warlock, Tempo Rogue, Tempo Priest, Totem Shaman, Control Demon Hunter, Token Druid, Dragon Hunter

Tier 3: Murloc Pally (it was never tier 1 or even tier 2. I have no idea why there are calls for nerfs. It's only good before diamond league, and then it sucks), Exodia Mage, other meme-ish decks

Omu Malygos Druid

Forest Warden Omu - This is in a tier of its own. I'm shocked that it isn't on top of every single list in this thread. It alone is going to make Malygos Druid a tier 1 deck. I'm playing it on day 1 and I highly expect it to be nerfed within a few weeks of release. Hyperbole? Maybe. But combining it with Germination is just too easy with all the ramp and card draw offered by Druid. Disgusting.

Lightning Bloom - Pure combo enabler. Innervate was nerfed for a very good reason back in the day. To now give that effect to Shaman, a class that lacks the kind of mana manipulation that's common in Druid is insane. This card alone will pull Shaman out of the dumpster that it currently sits in.

Potion of Illusion - Exodia Mage is back. Well, combo is back in general, but Exodia is back specifically. 2x Sorcerer's Apprentice with this and it's game over. My only question is will that deck be able to race the other combo decks in the format. I have my doubts. But if the above Malygos Druid deck gets nerfed, then this might rise into prominence. 

Glide - With all the combo enablers they released, they needed to print something to counter it. A disruptive Control Demon Hunter running this and Star Student Stelina will hopefully keep combo decks in check. 

Mindrender Illucia - Same principle as above. This card will give Galakrond Priest the ability to shut down combo by stealing an Omu or Apprentice. That seals the game. This card will be an auto include in every Priest deck. 

I guess you can tell that I'm very worried that this expansion will bring the rise of combo into an almost unhealthy power level in the standard meta. I've been VERY wrong in the past on these kinds of predictions, and I could very easily be wrong now, but this is what I see. And because of that, the cards that I see getting the most play are the ones that either enable those combos or can be used to shut them down. 

HSReplay elevates decks that are easy to play and are good against unprepared opponents. It's hard to make a mistake playing murlocs because it's generally correct to just play on curve. Meanwhile, right now, it ranks Quest Warlock as a tier 3 deck with a sub 50% winrate. And yet, that deck was being piloted very successfully in Masters and is played very frequently in high legend. Why? Because that deck skill tests you. If you don't know what you're doing with it, you're going to lose. A lot. If you do, you really don't have many bad match ups. Myself, I've used that deck to hit legend each of the past three months. 

So yeah, don't trust HSReplay. It only tells you which decks are going to be effective with low skill ceilings. Tempo Storm is what I use more than anything. 

Quote from Geoff >>

I have built Quest Lock just yesterday, but currently I have 100% winrate against them (6 games) - I appreciate it's not a considerable sample size, but the deck seems to work against them quite effectively. Also as mentioned above, Warrior is as hard counter as it gets.

 I can confirm. I got legend last month with quest lock and am currently grinding with it again. It's not 100%, because sometimes they just get a ridiculous turn and blow you out, but I have a good winrate against them. 

Best this year? Suttree by Cormac McCarthy. Best ever? 100 Years of Solitude by Gabriel García Márquez.

I actually did my climb this month with Quest Maly Warlock. It's really underrated right now.

Honestly, the meta right now is pretty diverse. You can climb very efficiently with a lot of classes right now. 

 alright through that how was that run for you, how long it take???

It took roughly 4-5 days for me to go from Diamond 5 to Legend with off and on playing intermixed with working and... Well, life. I had a 59% winrate.  But more than that, I found the deck fun, and I was never in a game where I didn't think I had a chance.

I'll use myself as an example in the current meta as I completed my legend grind last night playing 100% of my games from diamond rank 5 to legend with Quest Malygos Warlock (though the deck I used is irrelevant here). 

I was using deck tracker while doing this, so I have some data on the grind. The piece of data that's relevant to your question is that 14% of my 81 games played (a few were actually played at legend, but not many), were played against Priests, and all of them were post-nerf patch. 

So, if you were to have a similar sampling of classes as I did, that's 14% of your games that you would automatically have to count as losses. That may not sound like a lot, but if you only have a chance of winning in 86% of your matches, then you would basically have to maintain a 58% winrate against everyone else in order to have an overall 50% winrate. Bear in mind, that's a 58% winrate just to BREAK EVEN. If you look at Hearthstone replay, Highlander Mage currently has an overall winrate of only 52.79%. That's only data from the lower ranks of the meta and thus better players might have higher winrates than that, but still. The difference would not be extreme. 

Long story short, conceding your matches against all priests would make your climb to legend statistically almost impossible. Even if you feel like you're saving time by doing it, you're still shooting yourself in the foot. 

Hey, I'm running around Legend playing a silly Quest Druid deck with Nomi, so... Yeah, some of us are. 

1. Demon Hunter is not only still playable, it's still really good. You just don't auto-win anymore. You're only happy if you have your wins handed to you? 

2. If you knew that you could only afford to craft a few legendaries, why on EARTH would you craft them for a deck that you KNEW was going to be nerfed? Nothing stays Tier S forever. It gets nerfed. We all know this. 

3. Did you honestly want them to just leave the metagame like that for two freakin' weeks? With how oppressive that Tempo deck was? 

People... Just don't be dumb. Please.

Almost exactly the same. I'm free to play, and I keep my playing time at a minimum to prevent myself from putting off the important things in life. The only difference is I would have a different game downloaded onto my phone and laptop for my idle time. No big deal. 

I refuse to choose. The war between dogs and cats must end. Both are fuzzy. Both are adorable. And both of them love us unconditionally. 

*Hugs both his cat and his dog*

It has a high win rate largely because of how it performs from rank 20-11, where players are generally less prepared to combat those big board swings. But overall, the deck has one thing that it can do, and only really does it half the time. It's not consistent, and it lacks any way of reacting to its opponent. You see it now and again in the rank 5-1 bracket, and I have lost to it when they have gotten perfect hands, but that's about it. If their hand isn't perfect, they lose.
