New Death Knight Minion - Harrowing Ox

This card has every right to be good. (Practically) 0 mana 7/7 taunt, in a class where Frostwyrm's Fury basically just win games.

You have to simply respect cards like these in a class that can freeze, because for all intends and purposes this is just a tempo swing card that will more or less demand an answer or take 7 damage to the face.

The only problem that I can think of is redundancy, yeah this happens to DK alot. The card is not necessarily bad, but it could be that the specific rune alignment simply doesnt see any play, and so this might just get kneed in the balls through no fault of its own.

Okay, this is real nice excavate synergy. Unless you've had terrible luck, you probably have excavated way more than twice by turn 7. I'll take a 7 Mana 7/7 taunt plus bonus Frostwyrm's Fury thank you very much. I feel this would work better in a deck that tends toward high cost cards, but I'm not sure how well that will work with Frost Rune cards.

I don't think that this card will be that great, even though mana cheat has always been a strong mechanic in hearthstone.  For one, it's on a 7 mana card, which makes it not easy for early mana cheat.  Secondly, you have to excavate twice, and from what I've seen so far Excavate doesn't seem to be that strong.  Third, even if you are playing this into Frostwyrm's Fury or The Primus is very strong, it requires having both of the cards in your hand, which means you don't have as many Excavate to get the discount, or other early control the board cards that Frost DK has which means that you might just die from playing this.

Strong card, pretty much only because of Frostwyrm's Fury though. If excavate is good in pure frost them this might make the cut.

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.
