Good arena card. In standard this will be BAD.... Unless they add Fire Plume's Heart into the next core set. This card just seems meh, mainly because there are a lot of Big/bad taunts. And because discovers effect, you will mostly find the bad neutral taunts. 

Something amusing i just thought of, is what if it said: "Discover a taunt minion, it cost's [1] less this turn" + the repeat part. In this case i could see this getting some kind of play maybe? 

But so long as there is no big pay-off for Taunt warrior i think this sees no play. Last Stand is way better because it's draw and tutors + the manathirst effect.

So this is meh on it's own but only good with doubled stats from Last Stand or Lor'themar Theron. I don't think this will be good enough? They keep trying to make Taunt Warrior work, but it keeps failing. Honestly at this point i'm wondering if their gonna put Fire Plume's Heart into the next core set, just to TRY make taunt warrior work. 

At least this will be an amazing arena card though.

MUST-INCLUDE in a LOT of warrior decks. Warrior has always struggled with card draw, so getting Shield Block on a stick is incredible. Sure you need to have a weapon equiped and attack with it in order to use this effectively. HOWEVER Warrior does have [Hearthstone Card (Weapon Expert) Not Found] in order to tutor a weapon and warrior decks have always loved to run a few weapons in their deck. So this restriction is not that bad. And this fits well into Pirate warrior right now as well, as that deck probably likes some more draw. 

After the rotation, i think this card will still see a LOT of play. Warrior still has the Sunken City weapon package (And Suspicious Pirate i guess) and of course [Hearthstone Card (nellie, the great trasher) Not Found] will also still be there post rotation. So i think this card will see a lot of play....

The only problem of course is that enrage warrior is the only decent warrior deck right now, so this might be an amazing card but won't see much play unless it either fits in enrage warrior OR another warrior deck becomes good enough. 

Very good in shadow priest, probably will see play until the shadow priest package rotates soon.

In wild this is SCARY. Radiant Elemental + Mind Sear + Embalming Ritual + Test Subject = Rank 1 legend. 4 card OTK that only requires 3 mana to pull of. In b4 Radiant Elemental finally gets nerfed... or Test Subject gets "buffed" to 3 health.

Must-include for shadow priest, and other aggresive priest decks. 

This looks like a good card, but i dunno if it's good enough to make the cut in a priest deck. Does priest really need a Assassinate style card for 4 mana while priest already has tons of other clears. Like do you really run this when you already have cards like The Light! It Burns!?

Shadow priest can run it as well, but does it really want 4 mana remove a minion? Sure the healing can be nice, but i'm still not sold on this.

Restless Mummy but only if you hit 6 mana. This seems horrible, the main reason Restless Mummy was good was because it came down on turn 4 around the time where a 3/2 with rush could still remove a decent amount of minions. These days a 3/3 with rush is not good enough (Look at all the 3 mana 3/3s with rush that were printed that saw no play). You NEED the manathirst and when it gets it, it's way too late. This only looks decent for Arena.

So i'm guessing it uses your unspend mana if this triggers during your opponents turn? This seems horrible. Like this will probably summon 1-2 minions AT MOST during your opponents turn, and if it uses all your mana on your next turn then it's even worse. It does have good infuse synergy, but still i feel like this is way too slow. your opponent can easely play around this and minimize the number of summons thanks to the effect being a deathrattle. This seems really bad.

Very good 1/3, this will see play in a bunch of decks in both standard and wild.

Hold on a second... This is an epic card... Could this be it? Could this be... a PLAYABLE Mini-set Epic?!?!?!?!?! WOW, those are ultra rare!

Okay so this card is SCARY when abused. Untill rotation though i'm 100% sure Druid will abuse this alongside Wildheart Guff. That being said, i feel like Warlock can also abuse this thanks to Amorphous Slime and Infantry Reanimator, so lets be on the lookout for that. 

Hold on a sec, i just realised something. First Rivendare, Warrider and trigger the deathrattle. Next play Amorphous Slime and cheat out Thaddius, Monstrosity. Your opponent probably kills it, so just Ress it a few times with a few Infantry Reanimators once you draw all the horseman, just wait until Thaddius, Monstrosity discounts EVEN cards, then play all the horseman and kill them with a 1 cost Twisting Nether. TBH this might be way too slow, but still a fun combo.

Additionally in Wild this card will probably cause some interesting combos. This is honestly a scary card which might break the game at some point. OH and i just realised you can also cheat this out with Kael'thas Sinstrider as well.

5 star card, must-include for MANY hunter decks. This draws your Tracking, Wound Prey and Barbed Nets/Ricochet Shots. Questline hunter might make a comeback thanks to this...

Snipe but way better. This has infuse synergy and might leave some 1/1s on the board. This may see play, depending on the deck. The main issue of this card is that most of the secret package is in Altarac vallyet, which is rotating soon. 

More often than not it's a spell version of Dinotamer Brann. But is a effect like this still worth running? After all there are a bunch of cards that do something similar, but way earlier. It's an alright turn 7 play, and once you topdeck this on turn 10 you will be quite happy to play this. But i still feel like there are better options.

Interesting rune requirement but let's remember something. Because of the rune requirement Frost Queen Sindragosa can be discovered by both Frost Strike and Hematurge, so it's a card that will show up occasionally especially when a triple blood DK finds it. However i feel like a double frost + one blood or double blood + 1 frost DK deck will probably use this gladly. One thing to note is that this can destroy divine shield minions, which might be nice in certain meta's.

I personally really like those mixed rune decks, as it gives a lot more interesting options for deckbuilding so seeing non-triple rune decks get support is really nice!

Pretty sure it cant destroy divine shielded minions since the wing has to actually deal damage to freeze the target. Water Elemental doesn't work that way too.

Hmm, maybe i'm remembering the interaction wrong then. For some reason i remember a elemental summoned from Wildpaw Cavern attacking a divine shield minion and freezing it, but i might just be remembering that wrong. (It was quite some time ago) So i'll just remove that part from my comment to avoid confusing others. 

WOW, this is a cool card! From De Other Side, Front Lines and Proving Grounds meta incoming? Probably not. It is cool to see a Uther of the Ebon Blade kinda wincondition for every class though. But it might be a bit too slow, especially because you need to play "6 mana do nothing" multiple times, and even for combos with cards like Front Lines and stuff you first need to draw Rivendare, Warrider and have it die first. And it's really weak to transform AND silence effects.

This seems way to slow and clunky, but it wont stop me from playing this card a whole lot. I really hope the OTK animation looks awesome! Otherwise it would be a dissapointment. However i feel like it has an awesome animation, considering similar cards like Mecha'thun, the priest questline and the Uther of the Ebon Blade combo have cool animations.

Oh and in wild i bet you can do a lot of shenanigans with this card. I bet markmckz will have a lot of potential combos with this card.

This is a STRONG inclusion in a bunch of DK decks. This is a WAY better Dark Transformation with NO rune cost. Let me just compare these real quick:

Dark Transformation: TRANSFORMS a UNDEAD minion, so no synergy with deathrattles but it does only cost 2 mana. Additionally you need 1 unholy rune in order to use this card.

Construct Quarter: DESTROYS a FRIENDLY minion so no undead requirement, gives you a corpse because of the destroy effect + has deathrattle synergy, costs only 1 more mana than Dark Transformation and has NO rune requirement. And of course it's a location with 3 uses.

I can see this being a strong inclusion in Blood DK decks because it allows them to turn minions like Hematurge into a 4/5 with rush. Frost DK might not use this though. Some Unholy DK decks will probably experiment with this though, and i'm guessing it probably will make the cut in some lists.

This could easely be better then Might of Menethil because it costs 1 less mana and uses no corpses. Additionally, the spell requirement is easy to trigger in frost DK because that deck generates and copies a lot of spells. I can see this getting played, IF some DK deck needs more freezes which might be very meta dependant. One thing to note though, is that it only costs 1 frost rune which makes it actually quite flexible. I can see some kind of double blood + 1 frost rune DK deck show up and include this in order to stall/greed a little bit in terms of holding removal untill neccesary.

Man i love this new expansion, these new cards and decks are a lot of fu-- *Get's OTKd from full HP by Hunter on turn 6*

The only way to deal with that deck is either: "Just SMOrc before they can OTK", "Infinite Freeze their face somehow" and "Snipe Brann" And sniping brann only slows down their deck a little bit, you will still get OTKd at some point.

Honestly facing this hunter deck makes me feel like i'm back in the United In Stormwind meta again, and i hate it!

Seems good because you can cheat it out with Amorphous Slime, buff it with Twisted Tether and ress it with Infantry Reanimator. This might be a mini-sleeper card that will be quite good, but not broken.
