This honestly looks pretty bad and awkard on paper. Not only that but it adds the card in hand. While this is nice, it does leave it open for good 'ol Theotar, the Mad Duke and [Hearthstone Card (Mutanous the devourer) Not Found] to remove it from your hand.  And with manathirst you need to wait until certain mana totals in order to use this card effectively. And the final reward honestly seems only good in Druid because of Guff. On top of that Sire Denathrius is a way better finisher.

Still in practice it might be decent, but i honestly feel like there are too many challenges for it to be good.

Edit: After looking at theorycrafts, wow this card is busted. Apparantly playing both Sire Denathrius and Astalor Bloodsworn is very good. If Theotar, the Mad Duke steals one of them, at least you can still destroy them with the other.

Seems meh, but i think some kind of dragon priest might use it. After all, priest already has a few good dragons in standard. Emphasis on "a few", considering priest only has 4 dragons, 1 of those being a legendary. 

Wow, a spell damage card that prevents spells from going FACE? Unless we get some kind of Il'gynoth-kinda combo in the future, i dont see this getting played in any deck.

Edit: One of those combos AND a way to cheat this out.

Pretty bad card, and only "meh/decent" this expansion because The Demon Seed exists, but i dont think this card ressurects that archetype LUCKELY. 

Arena card. I dont see any deck wanting this honestly.

Brrrloc reprint with no tribe and the upside is only later into the game. Seems like either filler or a arena card to me. 

Seems meh to me. It's a worse Shadow Hunter Vol'jin most of the time, and i dont think this sees play because Soul Seeker does something similar. Honestly this seems like a arena card i guess? But even then you probably aren't happy to pick/play this.

Very sticky minion. But i feel like he costs a bit too much mana. Blood DK does have a bunch of ways to heal, but even so i feel like 5 health is too much.  But considering this says "return this to your hand" i wonder if it keeps handbuffs? If so then i guess that makes it SLIGHTLY less bad, but the HP requirement is still feels to big. And in triple Blood rune DK decks with Alexandros Mograine i think your rather keep your health as high as possible, rather then spending it on a 3/5 taunt.

I personally think this would be a lot better at 4 mana. 

Very expensive board clear, but it also generates corpses which Pure Blood DK can have trouble with. Additionally this really pumps up Corpse Explosion as well. This seems really good. It's kinda like a minion-Twisting Nether with a upside and a 5/5 body + tribe. Incredible minion, and you probably will need to play this after a turn 7 Alexandros Mograine. Because lets be honest, if your running full blood DK your running Alexandros Mograine, and Soulstealer really helps with stalling until you win the game.

Every control players dream card. This puts your opponent on a timer, and while their "clock" is running down you have to outlast them with lifesteal cards and removal. This is exactly how old-school control used to work: outlasting your opponent until they died to fatigue. But now instead of fatigue its at the end of your turns. Of course this requires running only blood runes, which is a big tradeoff. And this card can feel toxic at times. Additionally it's technically 7 mana do nothing, so you probably only play this when you can afford to play it. And it allows hyper aggro to probably rush you down if your unlucky with your card draw.

But honestly, Alexandros Mograine is just a really unique wincondition and i love this card already. Cant wait to finally play a control deck that actually outlasts their opponent again. It's been sooo long.

Edit: Brann Bronzebeard might be problematic with Alexandros Mograine.

Well, THAT is a way to end the game. Morgraine is every Control players dream card lol. This is like old-school control in terms of "outlasting your opponent" but now the timer is at the end of your turns instead of fatigue. Loving full Blood DK already! (Was kinda dissapointed with the 1 & 2 cost Blood Rune DK cards, but now that dissapointment is gone.)

Hmm. It seems Blood DK will probably be split into 2 different archetypes: Control DK and Handbuff/midrange DK. I guess this seems decent, but handbuff Blood DK might need some help with getting corpses, so maybe they slot in a unholy rune. Especially because unholy DK has Nerubian Swarmguard and Malignant Horror, which function well with handbuffs.

Honestly this Handbuff DK seems like Handbuff Warrior 2.0, which is very dissapointing. I hope the 3 rune Blood DK cards aren't handbuff cards...

Amazing value card, and getting 1 corpse isn't that difficult. This will be included in nearly every Blood DK deck because it can probably generate some removal option, and control decks often like some value cards.

Hmm could be decent. The highest attack minion can be a good thing to remove. However sometimes your in a situation where you rather kill the smaller minion instead. Just a random example: Spitelash Siren is on board + a minion with 1 more attack. In this case you preferrably kill the Spitelash instead. And in a case like that [Hearthstone Card (Aspyxiate) Not Found] is pretty bad, while if you play against some king of midrange/control deck [Hearthstone Card (Aspyxiate) Not Found] might be a lot better. This card seems really situational. Honestly i dont know how to rate this card, this seems too situational.

5 mana after Runeforging, so basically Arcanite Reaper with lifesteal. I dont know about this card honestly. You want to draw this using Runeforging, because playing this for 6 mana feels bad. This kinda reminds me of Libram of Judgment but that "costs 1 more" but can be discounted AND has 1 more swing, and that card didnt see much play, even in libram decks. I honestly dont think this will be a good card, maybe decent but not something your excited to add into your deck. Honestly i'm kinda dissapointed considering it's the Corrupted Ashbringer.

Deathstrike and Hearthstrike atleast are removal spells, blood controol could want/use

That is true, but i tried reffering the handbuff cards and Noxious Cadaver. (Weapon also decent in other DK decks including aggro, but not really counting it considering its pretty flexible.)

Just hoping the 2+ blood rune fit control archetypes a bit more then aggresive handbuffs.

Amazing minion. You spend 6 corpses for this reload or board swarm card, and you get all those corpses back after the 1/2 taunts are removed. This looks pretty good. The only problem with this card is that it costs 8 mana, but i feel like Blood DK might run this. Also if a Unholy DK runs a blood rune, they might include this as well. It's 1 mana cheaper then The Scourge and probably a bit more reliable i guess. And if DK gets any kind of mana cheat outside of Frost DK, you only need to cheat 1 mana in order to Boneguard Commander into Anti-Magic Shell.

But that being said, i'm still unsure if unholy DK even wants to run a blood rune, and it might be too slow for unholy DK. Maybe frost DK could try this out, so they can stall out more turns until they go for their wincon? Still i'm not sure if Frost wants a blood rune, because they probably prefer a Unholy rune for lots of corpses and ways to pressure their opponent.

Amazing weapon. This is only 2 mana after Runeforging and you can tutor this out of your deck with [Hearthstone Card (Ruenforging) Not Found]. It's a nice Fiery War Axe with the ability to get some corpses, which Blood DK enjoys. This also seems pretty good in Frost/unholy DK as well, because its a decent aggresive weapon and has corpse generation. This seems like a good all-around good weapon.

Good aggresive minion, but i'm not sure if Blood DK wants this unless they get some really good handbuff support. And handbuff effects have often failed in HS history, so i'm kinda scared that they are giving Blood DK these handbuff cards. Also despite looking good for unholy DK i'm not sure if they want to even slot in a blood rune.

I guess this has decent stats for 3 mana, and only uses 2 corpses for a good handbuff. I'm just not sure if Blood DK wants to include this card, unless they get some more synergy for it. This does look decent for Unholy DK, but i'm not sure if these handbuff tools will even compete against the amazing 3x unholy rune cards.
