Great removal for dual-rune decks like rainbow DK and plague-blood DK. This will see play, even if your not running this you will see this getting generated plenty of times.

Solid minion. 3 mana discover is nice, considering plenty of people already use the 2 mana amalgam to discover, but this also provides mana cheat which is almost always good. I think this will see plenty of play.

3 damage that can go FACE is.. alright? Spending 1 more mana for some value is alright i guess. This card will ONLY be good if excavate DK is good.

But one thing to note is that if you discover this from the DK Titans frost-ability, it will get spell-damage and be a 3 mana Fireball that excavates.

This seems like trash to me. Resummoning this seems alright, but the problem is that you have to play a 2 mana 2/1 minion. This messes with other excavate cards like Kobold Miner. And i feel like DK Excavate stuff is way too slow. 

Honestly with Excavate DK being this slow, i feel like this at 1 mana would be much better. And there is only a limited amount of excavate cards, so at some point you can't ress this anymore. Or if it was a 2 mana 2/1 with rush, it would be a lot better as well.

Generates a bunch of corpses, removal and activates undead synergy. Yeah this seems solid, especially in some kind of Unholy, highlander or rainbow deck. Will see play.

I'm not sure about this card. This seems good, but the rest of the package seems weak to me. Also you REALLY want to hit the legendary pay-off with this card, otherwise your probably cheating not that much mana. And i feel like DK has the weakest excavate package.

WAY better than Corpse Bride. This is cheaper, but has the downside of being less consistant. But lets be honest, you rather have 3 mana highroll summon Ragnaros the Firelord, then a Corpse Bride+8/8 Risen groom. 

This will see play in Rainbow DK, considering it needs corpse spenders like this. 

Triple Unholy DK might also use this, because if you play 1 copy of Plagued Grain before this, then you can summon a big minion early.

Seems decent, but isn't that great of a pay-off for excavating. Especially considering how SLOW excavating is. Just compare this to other excavate pay-offs like Antique Flinger or Badlands Brawler. And you NEED to play this alongside something big like for example: a TITAN or Collosal, otherwise your not really cheating any mana.

Also this is a frost rune card. Frost generally wants to burn their opponent down, i'm not sure why you want to play a slow archetype like excavate in triple frost DK. The Excavate package feels more like a Rainbow DK package. But the problem there is the fact that Rainbow DK wants mostly corpse generators and corpse spenders. And Excavate DK only provides Pile of Bones as a real corpse generator. 

Insanely good card. This generates a bunch of corpses, which is amazing in itself. The +5 max health next turn is mostly just a bonus you get every now and then, considering the large amount of 1-2 mana "destroy a minion" cards.

This card also has 2 decks that it can fit into.

The 1st deck is Rainbow DK. Rainbow needs some more corpse spenders AND generators, and this is both in 1 card. Must-include in this deck..

The 2nd deck is Unholy/Blood DK, a.k.a. Plague Blood DK. Plague DK with a blood rune now has a way to get more max health, which is nice. I like seeing a more niche deck like this getting more support.

Another thing to remember is that a lot of- if not nearly all triple rune cards are going to rotate, so which means triple rune will soon lose their main pay-offs, which means that multi-rune cards like this might get their time in the spotlight post-rotation.

Hm. This card seems pretty good, especially with the Excavate pay-off and other ress/deathrattle effects. For example you can also run this alongside the 1 mana unholy-rune spell that spreads deathrattles to adjacent minions. (Which will work well, considering Reska wants you to summon lots of minions)

The problem i have with this card, is the fact it's dual rune. This seems only good in Rainbow DK, or some kind of Excavate DK. (And i feel like the Excavate package will go in Rainbow DK) So i'm not optimistic.. for now.

However next rotation will be interesting, because a lot of good triple rune pay-off cards like Soulstealer & etc. will rotate, which might open room for exploring dual rune stuff.

Boulderfist Ogre beware. This card has good stats for the cost AND lifesteal AND taunt! Truly the most overpowered card of all time.

Okay okay, time to stop meming. I'm unsure what to think about this card. It seems like a fun card, and i like that team 5 dares to gamble with something like this. It might be too weak for meta decks, and the anomalys can backfire for you...

However i feel like this card was mostly created so people that hate linear gameplay can have a tool that makes each game more exciting. It's 100% a fun card, and for that reason i feel like people will play with this card even if it's not competative.. And every Casino deck will include this just so they can try the 1/20 for the "Add YOGG to both players hand" anomaly. (Did anyone Say Wild casino mage with 4 Yoggs, Yogg box, Yogg location, Rune of the archmage and the Amazing reno?)

I don't see this getting played in most decks... Unless it's some kind of Yogg Rogue with all the bounce effects rogue got from Festival of Legends.

So you probably want to play Yogg in a deck that runs a bunch of spells.. Or has ways to discover a bunch of spells. As for classes that could easely run yogg: Priest, Mage, Triple Blood DK, Shaman, Druid and DH come to mind. These classes could run Yogg without too much trouble. Altough non-mech Rogue might also be able to run Yogg as well. (Maybe Miracle rogue because they could use a cheap mind control or "board clear"?)

Lets look at the options:

Induce Insanity: Good one-sided board clear, can win you the game.

Reign of Chaos: Mind Control. We know that getting this effect for less than 10 mana is pretty strong thanks to Sylvanas, the Accused. This certainly can also win you the game.

Tentacle Swarm: An interesting option. This seems like a good option if you need to generate a wincondition, or if your in a control vs control matchup and want to generate some value. Of course the problem with this option is hand size, because you might not have a lot of space in hand for the tendrils.

Overall, i do see Yogg getting played a bunch in good decks and meme decks. There simply are a lot of classes that can make use of Yogg. Though with Yoggs thematic statline, don't expect to get more than 1 effect off UNLESS you can copy Yogg with cards like [Hearthstone Card (Reverbarations) Not Found].

Seems weak. The only thing i can see people do with this card, is some kind of YOGG Rogue which will bounce this card a lot.. Which sounds fun, ngl.

AOE on a stick... On a neutral minion? Hmm. Effects like this seems good, and spell heavy decks would probably like to play something like this. But still i'm not sure about this card, which feels to weird to say. I certainly will try this card a lot, because i like getting board clears in classes that normaly don't have acces to it.

Very good minion. It's technically a 3 mana 6/6 which is very strong. It summons 2 Treants which matters in treant druid. This is a good minion for every aggresive druid deck.

This seems quite decent. If you REALLY want to stall a turn, you can spend your mana to just try hold out which might matter.

Despite that i don't think it will be that good in Standard, unless it gets more support.

In wild though. Questline Druid will probably use this.

Mana cheat. 5 Star card.

Very strong elemental. And with Aqua Archivist this can be slammed down early. However i'm not sure if it sees play. Elemental mage simply doesn't have enough support in standard, and elemental mage has no real wincondition unless you mix elemental and Spell-school mage?

Eh i don't think it sees play.

Very strong card. Not only do you discover a spell, but if you have the mana you cast a COPY of the spell. Which means you can cast a spell twice.

Imagine the RNG fiesta from Void Scripture into Discovery of Magic, Molten Rune or Vast Wisdom.

Or the burn from Void Scripture into burn spells, Lightshow or Deathborne.

Or the annoyance if they discover Solid Alibi.

This will see a lot of play.
