I think this will see a LOT of play. Why? 1 mana destroy one of your random minions, and destroy your opponents TITAN seems pretty good to me. This is basically a 1 minion Plague of Flames except you can target the minions, which seems really good to me.

4 star card i.m.o. Seems pretty good, but i'm not sure about it. It seems pretty good for some kind of aggresive warlock deck.

In wild i think that this will be very strong in a The Demon Seed deck, especially with Crystallizer.

5 Star card. Discovering a minion from your deck is already a good effect, and summoning something with the same stats is nice. I've seen people in the theorycraft streams even pick Tour Guides and just summoning a 1/1, just because they needed more draw in the matchup. And being able to hopefully tutor out your Sargeras, the Destroyer is really usefull.

Additionally Forge of Wills can basically double the stats gained, and remove something on the board.

I think this card will see play for a long time.

FINALLY, Sargares is FINALLY in hearthstone. Me and many people have been waiting a long time for this day. So lets see how good i think Sargeras is.

First thing first, the abilities.

INFERNO!: Probably the option your picking if sargeras lives a turn, because you probably pikc Legion Invasion! most of the time... Assuming you have the board space for those minions.

Legion Invasion!: 9/10 times your probably picking this option. Summoning infinite 3/4s with taunt is very good, and basically wins the game against most aggro decks... Which you were probably winning against if you were able to play Sargeras. And against Control this also wins you the game, just because it's INFINITE minions, and 4 health is a LOT harder to remove than 2 health. 

To The Void: Twisting Nether but Sargeras doesn't get destroyed by it. VERY good effect. Twisting Nether still sees play, and this option is Twisting Nether on a stick. Very good.

The one problem i have with sargeras is that by running him, you no longer can run a Voidcaller package, because you need to use the battlecry otherwise Sargeras is useless. And because of that, he's weak to Dirty Rat which is in the core set.

But despite those problems i Hope am sure Sargeras will see a LOT of play. Especially when facing control priests, because they will copy your Sargeras a LOT and eventually those priest will summon 3/10 imps every turn. (if not bigger) And Sargeras is a very anticipated card, which people have been waiting years for. So Even if he's bad and lowers winrate, people will keep including him into their decks because it's f-ing Sargeras.

Also i wonder if some aggro/imp warlocks might also use him, because Sargeras will summon infinite imps. Might be too slow though.

Edit: Thank you Sargeras for the free packs, for the burning legion!

Florist for overload cards. I'm not sure about this one. A premium statted 2 drop that cheats mana makes me SCREAM OP AF in my head, but when i try ignore that and focus more on the synergy... Turn the Tides is the only newly printed card that overloads you, and i'm not sure if this is enough to really make overload shaman better. 

*Ahem* Horn of the Windlord. This is a 5 star card that will see play.

In case you need another argument why this is a 5 star card. Remember Doomhammer and Stormstrike? Well you can cast Turn the Tides even if your opponent doesn't have a minion on board, so i.m.o. this is just a better and powercrept version of Stormstrike, and Stormstrike saw a LOT of play even without Doomhammer.

The damage targets ALL enemies, which includes FACE. Which is really good. And you can setup a big turn with Lightning Reflexes and Flash of Lightning.

Speaking of Lightning Reflexes. It can generate some more Crash of Thunders and when you cast them all at the same time, that will be quite a lot of damage output. 

I think this will see play, because it can be discounted really easely and it's just a very good board clear that pushes FACE damage as well.

Flash of Lightning the turn before this in order to get this to 0 cost, and you can discover additional Flash of Lightnings in order to continue the mana cheat train. Also this helps discount Crash of Thunders or discover a few more Crash of Thunders. Actually when you discover a few of those and cast them all at the same time, that will be quite a lot of damage output.

Considering how popular Instructor Fireheart was, and all the current synergy this card has. I think this will be a mainstay in nearly every shaman deck.

This seems both amazing, and garbage. This having only having 1 attack doesn't seem that useful when your trying to influence where the 3 damage goes, but at the same time it's basically a 4 attack weapon which COULD potentially remove 2 minions, or remove a minion and deal 1 or 3 damage to your opponents FACE. I'm really looking forward to see whether this card makes the cut in control list, or some other shaman decks.

Hmm. This seems like something only control shaman could run, but i'm not sure if control shaman wants this...

Actually now that i think about it, maybe they want us to build a Control shaman list with Champion of Storms and Thorignir Drakes so we can summon a bunch of minions, and infuse some cards like sylvanas and maybe Denathrius? (Now that's a card i luckely didn't have to think about for quite some time.)

Eh, i'm not sure about this budget Neptulon the Tidehunter. This being a cheap threath might make it playable, but i'm still unsure about it. It just seems too narrow-use. 

Mana cheat AND draw. 5/5 star card, no need to elaborate any further.

Seems pretty interesting. If you cast Flash of Lightning the turn before playing this, and then play a forged Champion of Storms + Lightning Reflexes you will probably summon a bunch of 4/2s with rush which can help you retake a board or setup lethal. 

The main problem with the card is getting it forged. I don't think you want to play the un-forged version of the card, because rush is just so good. Which means that you probably have to setup a big turn for this card, which might be too slow.

Hmm. I still think this might see play, mainly because the tokens 4 attack is a really good breakpoint for removing a lot of minions, and as a 3/5 it can be pretty difficult to remove this minion and thus it might live more than 1 turn. Additionally there is a lot of support for this card already, due to the fact that nature is pretty much Shamans main spell-school.

5 Star card. Overloading sucks, and this really helps you by unlocking those overloaded mana crystals. Unlocking overloaded mana crystals is something shaman LOVES. Remember the questline? A lot of people would run the questline mostly for the first reward, which unlocks overloaded mana crystals. Additionally Shaman often lacks good card draw. This is a card that both unlocks overloaded mana crystals AND draws cards, which is why i think that Thorim is going to see a lot of play!

So the options:

Lord of Skies: Dealing 20 damage, a.k.a. "Delete your opponents TITAN". Seems alright.

Roaring Oceans: Insanely good board clear, and it goes FACE. Very flexible.

Shargahn's Wrath: Drawing 3 cards is nice, and shaman often struggles with draw. And this tutors overload cards, and tutoring certain cards is pretty good. 

Overall Golganneth seems like a pretty decent TITAN that will see play in a bunch of shaman decks.

Wow tutorring a minion from your deck and giving it stats. This is only good when rogue REALLY want's to tutor a mech. So IF the TITAN is good enough, people might run this in order to tutor it?

The problem i have with this card, is the fact that it's in rogue. Rogue has way better draw, and it's basically only good with magnetic minions so you can give a mech on board a explosive amount of stats. 

2nd best rogue card in this expansion i.m.o. (Only Gear Shift being better i.m.o.) This is just a really good card, the sparkbots can give so many good keywords and the +1/+1 stats can help mechs trade better or preventing them from being killed by certain removal cards. 

This card is also a bit more flexible than you might think. If a rogue deck has even a couple mechs, then this might be worth running already. And i feel like maybe combo rogue might experiment with this card, just because the sparkbots are cheap combo starters... Idunno about all of you, but when i play combo rogue i'm always stuck with only combo-cards in hand, and i'm always forced to play a combo card in order to activate the other ones. So having a bunch of 1/1s to start combo's with instead is really nice.

Also this might be pretty good on it's own, think about it. Your getting 3 sparkbots with random keywords, so if you magnetize them onto each other your getting a 3* mana 3/3 with 1-3 random keywords. (*Yes also +2 mana for the spell, but Preparation is a thing.) Also it gives 3 1 cost minions, so maybe miracle rogue might experiment with it? (Probably won't use it unless they can discount the 1/1s to 0 mana somehow.)

I think this might be a pretty good rogue card for multiple decks.

Magnetic Spider Tank but with stealth for 1 turn. Seems only good when generated by Flame Behemoth.

Wait a second, doesn't this kinda stealth get removed after you attack? So it's a slow magnetic minion that want's you to play this AFTER you attack in order to keep stealth? Why bother with this when you rather get a more agressive statted magnetic mech like Coppertail Snoop instead.

Hmm, this seems like a interesting card for mech rogue. 

If you magnetize this onto a minion it's technically a 2 mana 4/3 buff, and if it sticks around it generates more coins. And if a Sparkbot with windfury gets magnetized onto the minion as well, then your getting a lot of coins. 

Also a reminder that it's a magnetic minion, and thus can be generated by Flame Behemoth which might matter for some mech decks. And if one is generated by Flame Behemoth it's basically 0 mana after you attack.

Hmmm. On first look it's HORRIBLE, why would rogue want a card like this? But after thinking a while, this card will probably setup some kind of combo somewhere in the future. But that's in the future, right now this card looks like total garbage. These kinda cards are not something that rogues often play, unless it's required to do a combo/otk. 

Also a thing to note is the fact that it doesn't specify opponents like Enchanter, which means that ALL minions take double damage during that turn. Weird that they didn't specify the ALL, considering they do that with similar cards. Making your minions take double damage is only good in some kind of deathrattle deck, so you can proc deathrattles. That's about it, why would any other rogue deck want THEIR OWN minions to take double damage unless their is some kind of pay-off?

5 star card. 1 mana draw 3 is really good, and in aggresive rogue deck if your hands empty you can just draw 3 cards. This probably slots into miracle rogue already. Very good card!
