Just wow...

Priest have too many ways to heal your Hero with lifesteal, Hero power, spells and Minions.

Exactly the dame with warlock to selfdamage.

Really good card.

Assassinate+1mana, on a 3/3 stick, while being able to kill elusive minions. Seems good! Especially for warlocks, who often uses their hero power.

So basically just destroy a minion on a stick, because there’s hardly ever gonna be any times when you can’t damage/heal your own hero by turn 6

If this doesn't become a staple in both Priest and Warlock decks then I don't know what to say. Simple yet powerful; the fact that the effect is targeted takes this card to the next level.

For Warlock it's basically [Hearthstone Card (Kel'idan the Breaker) Not Found] except you also draw a card (and you don't get the occasional boardwipe, but w/e). Kel'idan is good enough to  see play in Questlock despite his secondary effect rarely activating....so being able to run two more is huge. It's essentially Siphon Soul, but instead of healing for 3 you get a minion...which is usually better.

If Warlock gets more ways to damage themselves for cheap this will be a staple for the class...probably even in Zoo.

Priest is a bit harder to justify....Granted, once you take damage there are multiple ways to use this efficiently (Renew for instance), but if we're being honest Priest doesn't really need that much removal anyways. I guess we'll see how consistent it is. Control or combo decks can easily play around it by just not damaging Priest so I don't see it being as much of an auto include.

Or just neferset thrasher as well!

Seems good, stronger in warlock than in priest since you can't always activate it in priest but in warlock the worst case it's playable at 6 mana.

Playable instantly in warlock, a little less in priest. It does cover priest's problem with elusive minions and 4 attackers.

Zoo will love this, and there's always more health changing cards down the line so this can only get better

Cool, simple, great! Very nice card for both classes, even more so in warlock.

it's a good control card, terrible for tempo tho, since you need to either spend mana to change your health OR have an effect like that set up the turn prior, in which case your opponent will spend THEIR turn removing THAT card.

Not particularly exciting but it's solid, I'm sure it'll see play.

Pretty good. It'll be interesting to see where this finds homes. 6 mana to destroy a minion is nothing new, but with added modular aspect of the card, you may find it in more tempo based archetypes.

quite powerful and easy to activate

Very good for Zoo-ish decks and could also work in some sort of Minion Based Buff Priest!

Very strong!

First of all I like the design so much: it is so simple, but fits both classes perfectly.

The effect is also pretty strong:

• Hardremoval - check
• leaves a body - check
• unconditional - no
• is the condition easy to fulfill? - check
• plays around counterspell and "elusive" - check
• cost ok? - yes

This card will receive a lot of hate.

Pretty much, I rated it 5 stars right away, because of what you explained.

First card that came to my mind is Vilespine Slayer. This is very similar, but can use your hero power to trigger the condition and it is cheaper. Easy 5 stars.

Big fan of this card, even if it ends up not being good.

Very nice to have removal + a body at a reasonable cost, but this might not see play because it isn't great against aggro, and is too slow for aggro decks.

If a strong midrange deck emerges in either class, ¿maybe dragon priest?, expect this to see play.

Strong card.

Lazy design. Which is exactly what I hoped NOT to see in bi-class cards.

Also, this is just a dull skeletal spellcaster. 

Where are my spooky ghosts?!?

I don't like this card at all. It makes Radiance too OP.

Just kidding! I really like this card. Flavor-wise, it is perfect for warlock/priest. And balance wise I think it is powerful enough to see play, but not really OP. Combined with the Hero Power it is a 6 mana 3/3 kill something, which isn't bad. But if you have something on the field that can trigger the ability without spending mana then you get a 4 mana 3/3 kill something, which is really powerful. 5/5 stars.

MY thoughts exactly

Wow! This is very open-ended. Dosn't matter if you took damage or healed, you get to destroy a minion. This one looks fun and very versatile. 

Super duper easy to activate in both classes for little to no investment.  Warlock likes hero powering anyway and priest has more than enough tools outside of their hero power to use this.  It also pushes both tempo and control in both classes, which I am a huge fan of.

Damn good card, like all bi-class cards. I really worry most of the nerfs are going to be to biclass cards. They all seem really high on power level. 

Effect is obviously nuts, effect is a lot easier to activate in Warlock naturally, since Lifetap is unpreventable and you can play around it in Priest by simply not going face (like in the days of playing against the Quest), but still, 5-star card all around.

Generally a 6 mana 3/3: "destroy a minion". This seems strong on paper, but it's quite.. different depending on the class.

For priest it's honestly at its weakest. I feel like Aeon Reaver Is WAY better, as it has +1/+1 compared to Brittlebone Destroyer. Sure Aeon Reaver is worse at dealing with taunted minions, but it has dragon synergy. Also for destroying big minions, priest already has Shadow Word: Death, Shadow Word: Pain and Forbidden Words. Brittlebone Destroyer Seems honestly really weak/bad as a priest minion. The only reason i think it exists is so that priest has a card like Aeon Reaver after GA rotates. The only thing the card NEEDS in order to be decent/good is a cheap self-damage (dual-class)card. like maybe a 0 mana card, or 1 mana at most.

For Warlock it's a WAY DIFFERENT story. For warlock it's basicly Keli'dan the Breaker from last expansion, but without the VERY situational board wipe effect. And you can use 2 copys of Brittlebone Destroyer... man Keli'dan the Breaker got powercreeped already... AND IT'S JUST THE NEXT EXPANSION! Also warlock has a lot of (cheap) self-damage cards like Flame Imp, which makes it come out faster than turn 6. This will certainly see play in zoolock, so they can get through big early game taunts. This card will probably make it so Soulbound Ashtongue also gets used in zoolock, just so that they can (hopefully) use Brittlebone Destroyer on turn 4. 

Basicly: Bad/outclassed in most priest decks, extremely powerfull in warlock/(self-damage)zoolock. So uh, why is this a dual class card again? Seems like mainly warlock flavor to me.

In a warlock deck can be an easy add if you need a removal. Can synergize well with other cards that inflict self dammage or use the same mechanics. In the worst scenario is a Siphon Soul with a draw effect and minion instead the 3 heal.

In a priest deck this card is slightly worse. Sure, you can heal yourself with heropower or some other card to activate Brittlebone Destroyer but the Warlock hero power is stronger. Apart from this Priest have more removal from which we can choose

Pretty awesome for a rare, easy requirement for both classes since your HP is enough.

It wears well its name , Brittlebone Destroyer ^^

Nice card, clean removal, easily activatable, good stats. All around solid I'm sure they'll get more ways to change their hp over the course of the XP so I can see this being played alot.

Super solid strong card, like most of the bi-class cards. 

Doesn't seem like it's worth running over Keli'dan the Breaker or Time Rip, but Vilespine Slayer saw play and this is around the same power level.

Effect is strong, but maybe not that interesting. Some people play to win, so this card will be used.

Excellent. This "change health" is a good way to solve the duality

REALLY POWERFULL

People are going to hate this card in both warlock and priest.

Love the design, but not sure if its good enough for Priest.

Nice control tech

Really nice effect. easy to complete the  requirement

Not sure Priest can make it work, but Warlock certainly can with Soul Fragments.

Turn 6 minion removal, but I hope you had something solid on Turn 5 to back this weak 3/3 up.

Great card.

Seems very strong to me!

Maybe we'll all be shocked by how slow it ends up being, but single target minion removal via battlecry is generally strong.

This card, with some others from this set, might finally give enough power to create a wild Even Priest deck lists. 

One of the best in the set by far, good with priest and warlock, cheap removal and leaves a body. I don't know, this card is just nuts.

Siphon Soul that leaves a body behind. Seems reasonable.

Very powerful effect for the cost and easy for both classes to trigger with 0/1 cost cards.

This is going to be a favorite for me, I can sense it, especially in the late game. Tap-BOOM to literally anything standing in your path is going to feel really good. . . even the anticipation of it, savoring those moments, knowing that soon, soon your opponent is going to drop some big dumb thing in your path to block you, threaten you, trying to force concession. . . Tap-BOOM. 

Realistically, this is a nice tool, but not a meta-breaker - someone earlier mentioned Siphon Soul and that's pretty legit. You'll be able to remove the Elusive guys as well with the Brittlebone Destroyer, which is niche nice (your days of ruling the meta are over Soggoth the Slitherer!), but both Warlock and Priest can generally handle threat removal. This is just a fun way to do it.

6 mana 3/3 destroy a minion in worst case

It's a good card, it will definitely see play.

Excellent and cheap hard minion removal

Priest already has a lot of efficient removal, but Warlock would love this card. Synergizes extremely well with the Soul Fragment package and Raise Dead. The only efficient single target removal Warlock has right now is Dark Skies, so a Warlock that runs either 0 mana activator would love more hard removal. It's also not bad in a pinch if you just Life Tap and remove a minion, basically Keli'dan the Breaker that draws a card (and deal 2 damage to your hero). Overall, more of a Warlock card than a Priest card and an amazing Warlock card at that.

I think this will be a decent addition to Even Lock in Wild as it gives them a fairly easy to activate single target removal.

My (other) favourite card of the set. The health change mechanic is so inspired and I don't care if it ends up being garbage, it's my garbage.

6 mana to play a 3/3 and destroy a minion is decent, but nothing insane. Doubt it'll see play in Warlock, perhaps it will in Priest though.

It can easily be 4 or 5 mana 3/3 destroy a minion because of how many health buffs warlock as gotten with souls.

Or even raise dead at 0 mana.

Demon can heal you if you draw it turn 4 or 5, which means this card will cost 4 or 5 mana to destroy a minion = insane

Soul Fragments you can draw on turn 4 or 5, which is the same thing, 4 cost destroy a minion = insane
