Seems pretty good. Decent stats Uncorrupted, and when corrupted it's really annoying to get rid off. Y'Shaarj, the Defiler priest will certainly run it.

Standard: Strong in control priests. Also good in Y'Shaarj, the Defiler priest. Ress is probably not running it, because it wants to only ress the most annoying cards possible. (Khartut Defender and Convincing Infiltrator. Thank Yogg those 2 rotate next expansion.)

Wild: I don't see this getting too much play. It just doesn't really fit in an already established deck. (That i can think off...)

Well time to play shaman with every transform effect in standard. WHY DID THEY BRING BACK THE WORST ARCHETYPE IN THE GAME?!?! Ress priest is super boring to play against AND play. But okay back to Blood of G'huun... Blood of G'huun is an elemental, meaning it gets ressed by N'Zoth, God of the Deep. It has good stats for it's cost and very powerfull effect. And we ALL know the 2 cards that are gonna get copied: Khartut Defender and Convincing Infiltrator.... wow so much fun.... 

Standard: Ress/N'Zoth, God of the Deep Priest.

Wild: ALL HAIL OUR BIG PRIEST OVERLORDS, Making Shaman for the first time in a long time by running almost every transform effect in the entire game. As if that deck wasn't tedious enough already. And it was never really "nerfed", considering that Barnes was the weakest card in that deck. I PRAY they will FINALLY introduce an graveyard system. (Graveyard system = You can only ress dead minions, ressed minions leave the graveyard.)

Incredible card for priest. Priest has this giant weakness of not being able to profit from healing cards when their always on full health. And G'huun the Blood God fixes that problem. G'huun the Blood God works well with Activate the Obelisk, and it counts as draw. And draw is something priests often lack. Were gonna see lot's of G'huun the Blood Gods. (And plenty of them from Galakrond)

Standard: Fits well in control priest decks, and galakrond priest. Not sure if boring Ress priests are going to use it though.

Wild: If ress priests use G'huun the Blood God in standard, then ress/big priest might run it in wild as well. Raza priest probably doesn't want it, because they don't want to take too much damage.

Glad to see more Dragon/Murloc hybrid cards, but why include support so late? Other cards for this archetype, Scalelord and Skyfin rotate next expansion, meaning that Redscale Dragontamer says behind. Also during the rotation a lot of dragons rotate, so that makes it even worse. But you can always just run it to pull a dragon. Now that i think about it, maybe it will fit in a deck together with Dragonrider Talritha? Meh i dunno.

Standard: Not sure what kinda deck it goes in. My guess is dragon murloc paladin or something? Doesn't seem like a good deck to me, didn't get enough support.

Wild: I don't see this getting any play. 

Wow, they made a better Ivory Knight! That's awesome! really flexible and can discover Librams in Libram paladin. 2 mana: "restore 9 health to your hero, add Libram of Hope to your hand" best case scenario, worst case scenario 2 mana First Day of School or "add a secret to your hand, restore 1 health to your hero". Seems kinda high rolly, but you discover so you at least have control over it. But it's still a very flexible card, and can just be a "get out of jail free card" by discovering a Consecration. 

Standard: Will see play in control Paladin decks like Libram Paladin and Pure Paladin. It's too good to not include.

Wild: This will be in heal paladin, even though it's a expensive deck that doesn't work that well. Maybe it will also see play in some kinda highlander paladin deck? Perhaps OTK Paladins will run it so they can stay alive, and try to discover Time Out!? In Holy Wrath, and heal Paladin it can help discount Shirvallah, the Tiger... Snack Run will see plenty of experimentation at the very least, that is something i'm at least confident of...

Extremely strong card. Also finally makes Elemental Allies a viable card on it's own. Elemental Allies fuels Grand Finale, and triggers Animated Avalanche. And in wild you can upgrade Lesser Ruby Spellstone more easely. Confection Cyclone also has great aggressive stats for it's cost. I have seen people compare it to Fire Fly, and i can kinda see it. Fire Fly is better turn 1, but Confection Cyclone gives more elemental tokens. So that's better for Elemental Mage Decks, and i understand why it's an upgrade. After all, Fire Fly is a neutral card, and Confection Cyclone is a class card. Class cards are supposed to be a bit stronger then neutral ones. Confection Cyclone seems like a solid card that i wish was neutral, just so Wild elemental shaman could have had acces to it..

Standard: Elemental Mage, Tiny spell mage will probably add Confection Cyclone and Elemental Allies, and it will see play/experimentation in highlander mage in some kind elemental package. (Not sure if it beats the dragon package, but it might make it so there will be a lot more diversity in highlander mage decks.)

Wild: This will see play in Elemental mage obviously, even though it's not the greatest of decks. But other then that i honestly am not sure... Mage decks in wild are generally just Casino, Secret, Highlander and Open the Waygate OTK... Oh and the meme that is mech mage. And i don't think either of those 5 decks want Confection Cyclone. Otherwise they would have slotted in Fire Fly, but they never did. 

Pretty good card. Basicly a "free" 2/3 body if you cast this alongside a secret on turn 3. Similar to Kirin Tor Mage i guess. BUT Game Master is a really scary card to keep alive, and will cause your opponent to play their removal to get rid of it. One thing i don't see people talk about is how great it is to have another "play 2 cards for the same price" card in a aggressive deck. This means you can empty your hand faster so you can draw more cards with Voracious Reader, and keep up the tempo/aggro. Also Game Master + Counterspell can be quite annoying when you try to remove it. If it sticks after turn 3, you can cast 2 secrets on turn 4. Seems pretty solid actually.

Standard: This will see play in secret mage, and other secret heavy decks. 

Wild: Secret mage might run it, I'm not 100% sure though. Game Master might be too slow, considering secret mage already has a lot of ways to play/cheat out secrets.

Kinda similar to Fire Elemental when it's not currupted. When it's corrupted it's a giant nuke. Firework Elemental seems like a better Omega Devastator in most decks. You can use it in Y'Shaarj, the Defiler decks, and it's just solid in other control decks. It's stats aren't the greatest, but it's basicly a removal option on a stick. Pretty good if you ask me. Also corrupting it is pretty easy, because of all the Deep Freezes, Puzzle Box of Yogg-Saron and Power of Creations mages cast.

Standard: Firework Elemental will see play in Elemental Mage, Control/Y'Shaarj, the Defiler mage and probably highlander mage.

Wild: This will see play in elemental mage. The ability to deal 12 damage is really nice, and you can heal for 12 health after playing Frost Lich Jaina. 

[Hearthstone Card (Mask of C'thun[Hearthstone Card (seems like a Reno the Relicologist replacement after he rotates, but it also seems like a combo piece. Maybe Mask of C'Thun gives rise to some kind of [Hearthstone Card (Keal'thas Sunstrider) Not Found] OTK Mage deck alongside Pyroblasts, cheap spells and Sorcerer's Apprentice. Also in most situations it's an upgraded Greater Arcane Missiles.

Standard: Will see play in this Kael'thas Sunstrider OTK Mage, and maybe in control mage after Reno the Relicologist rotates.

Wild: Not sure if this sees any play. It's ODD Costed, but ODD Mage probably doesn't want this card..

Also it's quite surprising that mage got a C'thun trowback card. I would have honestly thought shaman was going to get it, because C'thun battlecry shaman is a pretty decent deck.

Edit: Actually looked into this OTK some more, and it actually seems realy hard to pull off because i think Sorcerer's Apprentice probably wont discount the 3th spell from [Hearthstone Card (Kael'that Sunstrider) Not Found]. Just like how Eye Beam doesn't get discounted to 0 mana when outcast is active with Line Hopper. It's still possible, but you need every 1 mana spell to be discounted from Incanter's Flow or Emperor Thaurissan in wild…

INCREDIBLE 1 drop, WOW! Turn 1 Mystery Winner, turn 2 secret, turn 3 Petting Zoo. Seems like a solid play, and in the later parts of the game, it's still a good stopdeck. Generating a secret is a lot more flexible than slotting in a secret. Oh and by the way: R.I.P. Secret Plan, The card that almost never saw play. This is a case of really big powercreep, which is in this case good. Also by adding spells to your hand, it gets easier to get to the 10 spells requirement for Yogg-Saron, Master of Fate.

Standard: Will see play in pretty much every hunter deck. it's just that good. (Okay hyper aggressive decks wont run it.)

Wild: Will see play in secret hunter and the meme deck ODD Hunter wil run it so they can get acces to secrets from a good card.

It seems pretty good, but hard to trigger. Seems really good in deathrattle decks though. Deathrattle minions generally summon more minions, so the effect is easy to get in those decks. Considering this is a hard to trigger secret, it will be hard for your opponent to know which secret you played. This is probably the last secret they check for. 

Standard: Will see play in secret hunter.

Wild: Will probably see play in Secret hunter and maybe EVEN Hunter.

Which animal companion will it summon?

Seems like an interesting card that is hard to remove. But it's more of a control hunter card. And "control" and "hunter" don't go together well. 

Standard: I dont think this will see play. Maybe experimentation at least.

Wild: Hunter and wild? lol.

Hey it's a OVERKILL card. Also this is kinda similar to our great meme monkey Knuckles. Buffing Trampling Rhino will be easy though, and in the reveal stream they said that during internal testing it is/was generally around 8/8 of stats. (I know internal testing, sounds kinda weird with the amount of broken cards released previous expansion... maybe they just started doing it?) Also Trampling Rhino is 5 mana, meaning it can be tutored with Guardian Animals.

Standard: Trampling Rhino will see play in some kind of Beast Aggro Druid, and i'm pretty sure someone is going to use these to make a OTK Hunter deck. (With Beastmaster Leoroxx.) Won't be a good OTK, but we will see some video's/clips of it.

Wild: Hunter in wild is a joke, and so is this card. If you wanna go for the memes, don't go for Trampling Rhino. Instead use our boy Knuckles. It's easy: first we cast Dire Frenzy on Knuckles, and then weGuardian Animals to summon them and go monkeh all over their FACE.

Super solid card. Great for treant druid, and a druid deck that runs Greybough. Also it can draw you a card, so that's always nice.

Standard: Treant druid will use it, and Greybough druid. (Honestly why doesn't Greybough count as a treant?)

Wild: It's ODD Costed, but ODD Druid is one big meme. I don't think any other druid deck wants this... Well at least Gibberling and OTK Druid don't want it, and those are the best druid decks in wild right now.

Better than Bite, but those kinda cards have never seen play. Maybe the Y'Shaarj, the Defiler synergy can chance that? This also reminds me of Feral Rage, which is funny enough a Whispers of the old gods card. Druids have always like a way to gain armor though, so i wouldn't be surpriced that it will see play.

Standard: Y'Shaarj, the Defiler Druid will use this for survivability and removal. Actually you can see Moontouched Amulet kinda like single target removal, which is something druid really lacks.

Wild: Wont see any play. I think of any deck that might run i... oh yeah Gonk druid exists.. Maybe that meme deck wants it.

Fits really well in Embiggen druid in standard, and it fits in Kael'thas Sunstrider Druid. Seems like a solid card. Weak on first glance, strong when you look at the synergy. (Mainly when buffed by Survival of the Fittest.

Standard: Kael'thas Sunstrider Druid, and maybe spell based token druid decks? But those prefer little to no minions...

Wild: Not sure what kinda deck you want to slot this in. Cards like this have always been good in wild, but i'm just unsure as to what kind of deck wants this. OTK druid really doesn't want this, because its bad with Juicy Psychmelon.

Interesting card. good stats for it's cost and can keep growing. This will either be a bad card, or a card people sleep on. But time will tell i guess.

Standard: Will maybe see play in Aggro DH. But that's it i guess.

Wild: Wont see play, unless you count the meme deck EVEN DH. But i think that even that great meme deck doesn't want it.

Incredible card. Counters aggro, and aggro DH can use this in order to get a weapon + clear. Super solid card. RIP Felsteel Executioner, it already got replaced in the same set it came out. 

Standard: Great for aggro DH and Soul DH.

Wild: ODD DH loves this card. This helps against Gibberling druids that didn't buff turn 2. (or turn 1 with coin) If YOU have the coin, you can coin it out on 2 in order to deal with Patches the Pirate that got buffed by Embiggen. Solid card, and you gotta mulligan for it when playing against a druid.

Incredible card. Free trading for soul DH, and you can use this alongside Aldrachi Warblades to heal and remove a minion. (Or go FACE) Solid card.

Standard: This will go in Soul DH, Lifesteal DH and Aggro DH.

Wild: Won't see that much play, i guess. ODD DH prefers cheaper spells like Twin Slice and the 3 slot is already quite.. contested in ODD DH. 

Turn 5 Skull of Gul'dan is gonna be back, if you don't clear Line Hopper. Line Hopper also has amazing stats for 3 mana, so it fit's in aggro very well. In the reveal stream we did see that Eye Beam couldn't get it's cost lowered to 0 mana, but i guess it's because Eye Beam is hard coded to cost 1 mana when outcast. Just to clear things up.

Standard: This will see play in aggro DH, because of synergy with cards like 1 mana Spectral Sight, 0 mana Crimson Sigil Runner and free Consume Magic. "when the face plays taunt, we still go FACE." 

Wild: Good stats and ODD Costed, so it would seem like a ODD DH card. But i'm not that sure about it honestly. A LOT of Outcast cards are EVEN costed, so their is not that much benefit to include Line Hopper. (Only good ODD outcast cards are Crimson Sigil Runner and Consume Magic.) Actually now that i check it, Dreadlord's Bite seems nice to cost reduce, so you can play some other stuff alongside it... Actually i change my mind, Line Hopper MIGHT see experimentation. But that's all i can think off.
