For mage: This has some really good synergy with Conjurer's Calling and Khadgar. 

For Rogue: Clearly has a lot of synergy with Bamboozle, as it will pretty much give you a "free" 8 drop. 

For both classes: There are some deathrattle minions 5 mana, like Al'ar, Abomination and Recurring Villain that you can get from this. In wild you can highroll into Rotten Applebaum, [Hearthstone Card (Anubiseth Sentinel) Not Found], Feugen, [Hearthstone Card (Stallag) Not Found], Sludge Belcher and Skelemancer. So that's pretty good as well. (Note and you can of course highroll into Zilliax as well) This card is very RNG dependant.

Also the "negative effect" isn't as bad as you make your opponent use clears/removal to find out which minion dies after taking damage, and you can always pick the worst minion to get this effect. Also around the mid-late game (turn 5+) your opponent will generally have big clears that woud deal with a big board anyway, so if a minion would take damage around this part of the game, it would have most likely died anyway.

Mage will use Jandice Barov mainly in highlander decks, maybe some new version of Conjurer's Calling mage, and because it's super random it will certainly, without a doubt be used in WILD Casino/random mage.

Rogue will Jandice Barov in secret rogue to abuse the Bamboozle synergy, and in tempo rogue because Jandice Barov can give quite a tempo swing.

So their Totems and Treants in one? That's interesting.

In shaman: This boosts the power of totem shaman even more. They are really pushing this archetype i guess, even though it already was quite decent/good before. Also this is both removal and it has overload synergy. This will fit in a LOT of shaman decks, and will see a lot of play.

In Druid: This will certainly fit in treant Druid, and it gives druid some way to mass clear a board. (Sometimes) This will also see play in spell/Glowfly Swarm druid. This looks also like a solid spell for druid, this card will also see a lot of play in druid.

I like it! Good stats for it's cost, and spell damage +1 on it as well! This also has good synergy with that new mage/shaman legendary. Also because of it's low cost this might also see play in some sort of burn mage deck. This card will see plenty of play, might just be the kinda card you slot into your deck because you needed something cheap.

Good for token druid. Not much else to say about that.

Hunter: I don't see that much synergy with hunter yet, because hunter already has Fresh Scent for buffing, and hunter already has a lot of other cards they prefer to play. But it might see play in quest hunter i guess

Decent in paladin, In standard this might get used in Quest Paladin so they can abuse the deathrattles/hero power synergy stuff even more. Also this will see play in Pure paladin, as pure paladin LOVES any kind of paladin card. 

In priest it's GODTIER. This is the cheapest way in standard to copy a minions deathrattle, and priest can use this to do the fellowing insta-win combos:

Insta-Win Combo #1: Gift of Luminance + Convincing Infiltrator. "Gr3Et7Ng2 F3lL0w HuM0n2." (any opponent just concedes.)

Insta-Win combo #2: Gift of Luminance + Khartut Defender. "0uR H0m3S, oUr 7uM8s" (Super effective against DH's in particular.)

This has incredible synergy with ress priest and Big priest, so i'm sure this will be used a lot, and i wouldn't even be surprised if this wil get nerfed to 4 mana, just because of Priest's sins. Needless to say, I HATE THIS CARD ALREADY. 

Good statted, and taunt. Solid minion. Cheaper and better [Hearthstone Card (Rottem Applebaum) Not Found]. It's 1 mana cheaper, and the healing is right away instead of a deathrattle, this makes it all-around way more useful.

For Shaman: Shaman NEEDED healing AND taunt, so this is EXACTLY what control shaman needed. This will 100% see play in nearly, if not every control shaman list.

For Druid: Lucentbark Druid. The problem with Lucentbark druid, used to be the fact that their wasn't that much health to heal, but after the Broken DH class released, the problem became the lack of healing. This certainly helps out early to mid game, and late game it still helps "ress" Lucentbark. The problem, to me is the fact mage/shaman just got Devolving Missiles, and Zephrys the Great can give other transform effects. Also Silence effects still exists, so i'm still VERY unsure if this deck will finally become... not even good, but decent? 

So for Shaman it's a SLIGHTLY better Despicable Dreadlord at best, as this can hit FACE. BUT the damage increases with spell dmg. However i don't think this will EVER stay alive longer than 1 turn, so you gotta have a lot of spell dmg on board for this to work. And opponents always LOVE removing spell damage. And this also doesn't have that much synergy with Squallhunter, because of Squallhunters overload. Unless you play it AFTER [Hearthstone Card (Ray Frostwhisper) Not Found] survives a turn, which is VERY UNLIKELY. 

For mage it has way more synergy and better cards like Azure Explorer and Kirin Tor Tricaster. This will probably see play in a more blast/burn mage archetype.

Seems like a good control tool. Good stats for it's cost, you generally see these stats on legendary dragons like Malygos and etc. It's better than spells that do this kinda effect like Subdue, mainly because this actually removes a minion. HARD removal (that is not a 2 or more card combo) is something paladin needs, so this will see a lot of play.

AMAZING CARD. This is something that can be used in nearly every deck. (Mainly to get more PRIME's). This is nice for deathrattle rogue, Casino mage (more prime's = more RNG), and many more decks.

Also this thing is going to be NASTY in FACE Hunter, with all their Leper Gnomes and stuff.

BUT i'm the most afraid of the things PRIEST is going to do with this card... copying the deathrattles of cards like Convincing Infiltrator, Chronobreaker in dragon priest, and perhabs even Grandmummy and EVIL Conscripter in some kind of zoo/tempo priest thats coming up. 

This card has a LOT of potential in both standard and WILD. 

now THIS. THIS is what feels like a rogue-ish kinda spell! I love the flavor of this card. This also reminds me a bit of [Hearthstone Card (Myras unstable element) Not Found], except you can fit 2 in your deck, and it doesn't delete your deck. Super helpful for finding some solution to a problem. Don't have Flik Skyshiv in hand and you need her? Secret Passage and pray you find Flik Skyshiv. Also helps you find lethal in some cases, if your willing to bank on the chance you find a Eviscerate.

a Cobalt Spellkin that can actually fit in aggresive decks, needless to say i'm actually kinda scared of this card. This in DH CAN tutor more Twin Slices. Also it works well with spellburst, and will certainly see play in RNG decks like casino mage, cuz random wins games. (and i love it, keep charging my Yogg-Saron, Hope's End)

Also this also works with [that one forbidden WILD mage quest we don't talk about] as it has a lot of spell-chaining things going for it with cards like Magic Trick. This card looks really good.

This card is AMAZING. most combo decks will run this. You don't want to top-deck your wincon because you want to discount it first with your hero power? (Quest Warlock) Now that i think about this, this might as well be a warlock legendary, as it also synergises with the new legendary. (So you can keep 1 big demon in your deck at all times)

This card is just amazing, and it's NEUTRAL. The FIRST neutral weapon in HS! This card is so creative, i love it.

This looks like a good combo card, helps getting to your Malygos sooner, and works well in quest Warlock. Also pretty good in big decks like Recruit warrior and perhabs big warlock. This card looks pretty good to me, and it counters/gets countered by most new DH cards like Glide. So good for combo's and bad for most other decks i guess. Very interesting card though, this feels like an legendary effect. (*ahem Infiltrator Lilian)

It has.. mediocre stats for the cost, but it does have rush so it impacts the board immediatly. It's kinda a cheaper pre-nerf Keeper of the Grove, but I feel like Consume Magic will still be used instead of this, as DH LOVES card draw. Also i don't think pre-nerf Keeper of the Grove would still see play these days, so i don't think a 1 mana cheaper version will. i still feel like it's just mediocre for DH. Which is weird, because it would see a lot of play if it were neutral. This basicly just shows the ridiculous powerlevel of DH i suppose..

OKAY what the?!?!? Okay so this is super annoying and will get hated.. A LOT. Decent stats as well. At least it's an outcast card, but we all know the outcast condition is pretty easy to complete in DH. This will CERTAINLY see play in aggro/tempo DH so completely ignore/remove a board clear from your opponents hand. Actually no, this will see 100% Play-rate in every. single. DH. Deck. Till. It. Rotates.

Needless to say, this will CERTAINLY end up getting nerfed. This is basicly Madame Lazul, but WAY BETTER.

Interesting card, but i feel like it simple is still too weak, which is kinda funny. The best class that can use this is Mage with all their cheap spells, and twin-spell cards. Also it's only 1 dmg, so it's basicly just a Elven Archer, and Elven Archer sees like 0% play? I feel like this might be more of an arena card? Arena players LOVE pings. But i feel like even in arena it might get overshadowed a lot, mainly by cards such as Fire Plume Phoenix, if it's in the arena rotation. 

The only other deck that might CONSIDER using this is Raza Priest in WILD. They LOVE being able to play cheap cards multiple times, so that they can go FACE with their hero power even more. But even then, they still need a bunch of spells in their hand/deck in the late game. Doesn't see that practical to me.

Great with Playmaker and Steeldancer. Warrior used to love playing Darius Crowley as removal/board presence, and this is arguably a better Darius Crowley. Sure it might have less survivability, but Darius Crowley also gets removed pretty much right away, so i still think +1/+1 for a weapon > +2/+2 stats (-health for trading). And it also works kinda like Captain Greenskin So i guess you dont NEED to run the pirate package to get a similar effect regularly. But it might also get runned ALONGSIDE Captain Greenskin in order to buff your weapons even more.

Bad synergy with the prime, but i feel like we must not underestimate this card! There must be a few big demons still yet to be released that can make this card broken, and it tutors a card from your deck. Tutoring cards from hand/deck has previously been extremely strong. Just think about Patches the Pirate, Voidcaller and Call to Arms. Sure this is more of a late game card, but this gives so much mana discount. If you ONLY summoned a single Enhanced Dreadlord with this, you already saved 8 mana. 

Also in wild this can tutor Mal'Ganis and Voidlord. This is really good. also if your holding 1 Voidlord in hand, and you have 1 in deck. And you play Archwitch Willow you get 2 Voidlords on board. This cheaps out 18 mana! This card seems insane.

This seems really good with the newly revealed legendary. It's unfortunate that Bloodsworn Mercenary is still in standard, but i feel like this new card might be better, if there will be even more good rush minions shown. Just a good card.

Whoops should have probably taken a better look. Thanks telling me! Now i'm wondering why i thought it was a demon in the first place... lol
