This looks more powerful in Druid than in Shaman, as the more expensive Shaman spells in standard right now are symmetric board clears. Druid also has a weakness of lacking removal in general, so Speaker Gidra helps shore up that weakness. Probably only sees play in Quest Druid that may run a Malygos win condition to serve part of the role Wardruid Loti did before she was rotated. I imagine you don't run Gidra in Spell Druid as you only want to run essential minions in that deck for Fungal Fortunes.

In both classes, I don't think Guardian Animals makes sense in a deck in either class right now, especially since it's anti-synergistic with Embiggen.

In Druid, the only archetype that might consider this is Embiggen Druid even without Guardian Animals. However, I don't see room being made in the deck for Teacher's Pet, I think you just run Twilight Runner instead.

In Hunter, the only archetype that would consider this is Deathrattle Hunter, which I don't think is as strong as Highlander or Dragon Hunter.

This seems powerful in Embiggen Druid. A great pull from Strength in Numbers and the stealth is nasty with the Embiggen buff. Note you can't run Guardian Animals in Embiggen Druid reliably as you can't pull 5 mana beasts with it post Embiggen. I think the archetype ultimately is overshadowed by Spell Druid and the potential archetypes of Malygos Druid and Token Druid, but having this will help boost the archetype's power level.

Not gonna lie, I'm a little scared of this little Gibberling. It could have the Imprisoned Scrap Imp effect where if you get it in your mulligan in your Token Druid, then your win rate sky rockets. The issue is, you need some specific cards to support it early on like Innervate and Lightning Bloom and a buff card whereas with Scrap Imp you don't need as much setup. I would still keep my eye out on this one.

EDIT: I just tested if Embiggen screws the recruit of Guild Recruiter and Oaken Summons and it does, so Guardian Animals doesn't work in Embiggen Druid, which is the only deck I thought this might see play in. RIP.

I see no applications for this in Hunter in standard as it's too slow for most Hunter Archetypes. This might be fun in wild with Witchwood Grizzly though.

A cheaper Rampage for Warrior, nuff said for them. For Paladin, having a damaged minion is a lot harder than for Warrior, so placing this buff on a minion that can attack isn't as likely as a scenario. Overall, this is really more of a Warrior card to fit into already existing Warrior archetypes than a new inclusion for Paladin.

A cheap way to copy Spirit Jailer and Void Drinker in Warlock for your Soul Fragment synergies. Good to play without the outcast and playing it with the outcast is a nice added bonus, though I think this doesn't make sense in aggro decks as they'd rather run a card with better standalone tempo instead. This makes more sense in a slower Warlock with the mentioned demons than in DH to me as I think DH cares more about the tempo as a win condition as Big Demons in DH isn't a consistent win condition and the archetype isn't getting enough support to help it.

I think this is a great payoff for the Soul Fragment package, but not a game-winning payoff. Soulciologist Malicia is a great card, but she and the Soul Fragment package doesn't provide the same inevitability that Blastmaster Boom and bombs provide for Bomb Warrior. I still think Malicia will see play, but 1) she demands that you run the entire Soul Fragment package for either class and 2) you have to run a game-winning package alongside the Soul Fragment package. I think this is easier to do in Warlock than in DH as Warlock as better late-game win conditions like Lord Jaraxxus (remember Demonic Studies?) and Arch-Villain Rafaam.

Of course the comparison is made with Despicable Dreadlord, but I think there is some context missing for what made Dreadlord competitive. In Dreadlord's time, it mainly saw play in Zoolock as a way to counter a very prominent archetype at the time: Dude/Odd Paladin. While Ras Frostwhisper certainly has its use with the prominence of lackeys in standard, I can only see him going into tempo-based decks in either class, just like how Dreadlord mainly saw play.

I think Mage has more use for him than Shaman as Shaman has other more synergistic 5-cost plays like Totem Goliath and Shield of Galakrond. Maybe in a Burn Shaman to utilize the spell damage upside, but Burn Shaman cares more about using spell damage to go face with cheap burn rather than a minion that doesn't go face well. Might as well just run Cumulo-Maximus instead.

For Mage, I'm skeptical of how consistent the spell damage package and how much spell damage you can keep on the board. Yes there is Mozaki, Master Duelist, but she's a one-of in your deck.

Overall, I don't think Ras Frostwhisper will see consistent play in either class as he is low impact at a base and requires too much inconsistent support to increase his power.

The Demon upside over Wisp is only useful in Warlock and DH. Even then, both classes have better cheap Demons if they wanted that synergy like Spirit Jailer just to name one.

This is a nice support tool for Big Paladin and Big Warrior. I think Big Paladin is so close to becoming viable, but now with this and Plagued Protodrake I think the archetype can get there. Imagine pulling out Kael'thas Sunstrider with Duel! on 5 and then playing First Day of School into Commencement. Big Paladin is a deck I'll definitely try to see if it now works. I think Big Warrior doesn't work as well even with this new addition as its swing turns come online much later in the game than what Big Paladin can accomplish.

After seeing all of the beast support cards for both Druid and Hunter, I don't think she is very impressive in Hunter. Druid might be able to make the copy effect work in Embiggen Druid with Marsh Hydra and Winged Guardian, but the big stats without the copy is usually enough to threaten the opponent. The buff deck aspect also doesn't seem that appealing as it's a weaker and more restricted deck buff than Embiggen. Overall, I think she doesn't have much of a chance to see play, but it's possible that after the next rotation she makes more sense.

I think this is a good back up plan for Zoolock if they don't hit Imprisoned Scrap Imp. I think this is tougher to see play in a Tempo Buff Priest as they don't have nearly the same level of card draw as Warlock, especially since this has anti-synergy with Voracious Reader. Disciplinarian Gandling is practically a win condition on turn 4, which makes me think it has to see play in at least Zoolock.

This has two main uses going for it: giving your minions that just entered play rush and killing off friendly deathrattle minions. DH doesn't want to run this since they don't really have those synergies. Hunter might run this weapon, but I don't see it in Highlander Hunter as Desert Spear is the more tempo-oriented weapon in that deck. If a Deathrattle Hunter pops up, they will run this as a cheap proactive way to trigger deathrattles. I don't see a Deathrattle Hunter working this expansion, but that doesn't mean it won't work an expansion or 2 from now.

I think Warlock will more consistently run this than DH, because I think DH Soul Fragments make more sense in Tempo DH with the tempo package of Spirit Jailer, Marrowslicer, and Soulshard Lapidary. A lot of the Warlock Soul Fragment cards overlap in synergy with the dual-class card they have with Priest, potentially allowing for a Soul Fragment Handlock, especially since we might see Lord Jaraxxus come back with Demonic Studies.

I think any deck that is considering any Soul Fragment payoff cards will run this. Tempo DH would love to just run Soulshard Lapidary and get its effect, and with just this and Marrowslicer, that's a serious boost to Tempo DH. I think Zoolock on the Imprisoned Scrap Imp and Hand of Gul'dan package to fit in any part of the Soul Fragment package well, so I think the only way Warlock runs Soul Fragments is by including all of the cards in a slower deck like Handlock. However you slice it, if you run Soul Fragment payoff cards, you run Spirit Jailer.

Ace Hunter Kreen looks more situational to me despite his crazy effect. First, I don't think he sees play in DH because they already have good hero attack buffs to help contest the board so their minions can go face, and they don't care about losing health in most situations. In Hunter, I'd compare this with Houndmaster Shaw. Shaw could be played proactively on 4, since it had a great stat line for 4 mana, and gave any minion you played the following turn rush to defend Shaw for potential future turns. Kreen is like a reverse Shaw: where Shaw gives your minions initiative, Kreen requires your minions to have it, so you can't really play Kreen on three unless you have a 2-drop to trade into an opposing minion. Hunter really likes proactive minions too much so I actually think he doesn't find room in Highlander Hunter, but maybe Quest Hunter?

Such a terrible top deck. Also, it takes about 7 friendly minion deaths to make this interesting, and that isn't usually happening by turn 5 when you'd like these stats the most. Blood Herald is just too slow and inconsistent for either class to run.

So, you've manage to succeed in putting multiple beasts into play. What's the payoff? Maybe kill a minion for 1 mana? The investment in this card isn't worth its payoff.

Pretty crazy card for both standard and wild. Priest in both formats right now is strong against aggro, but weak against combo. This gives Priest very consistent combo disruption. As long as you time her right, Mindrender Illucia is a Dirty Rat that will always hit your opponents combo piece, so long as you have the mana to play and get rid of it. Maybe this puts Raza Priest over Quest Mage as the top deck in wild? It also keeps Questlock and potential Maly Druids and Exodia Mages in check. It does require you to draw the one-of card in your deck. In standard, it's harder to draw her consistently with less card draw available to Priest, but Sphere of Sapience can help with that. A staple in any control-based Priest.
