The win condition is any of the three Legendaries. The Lich King should be obvious. Moorabi can copy your opponent's win condition. And White Eyes ... just try to play him as many times a possible. (He's the main target for Ancestral Spirit.)

Freeze your taunts with impunity, especially Tar Creeper and Stonehill Defender.

Update 9/8/17

I continue to work on this deck, albeit playing at low ranks. I don't think I've quite got it figured out yet. But I'll keep trying (especially since I don't have the KFT cards for most meta decks right now).

Comments on cards:

• • Glacial Shard - obviously not great for tempo, but it is the main enabler for Moorabi and sometimes can just help you survive by stalling too.
  • Ancestral Spirit - has won me a LOT of games. While it's intended to go on White Eyes, it can be good on any high-value minion, especially taunts when you're trying to survive against aggro.
  • Brrrloc - this wasn't as good as I hoped in the role of just a 2-drop; it's usually better just to use your hero power. While this can be useful with Moorabi, it felt like it was often just a dead card in hand, and one too many freeze effects, so I cut one copy.
  • Cryostasis - is a dead card less often than I worried it would be. I never use it on enemy minions, just on my own taunts and totems. I might cut it, though, because it never seems to combo with Moorabi. It's just a buff card.
  • Devolve - added a second copy, as it's often crucial to survival against big boards.
  • Dirty Rat - I took this out. It never seemed to fulfill its intended role of being a big speed bump to aggro, and a number of times it screwed me over by pulling out big things (despite my "read" that the opponent didn't have big things in hand).
  • Hex - I took out one copy, partly because I'm anticipating the nerf. Might put it back in though. You all know Hex, I don't have to expound too much about it.
  • Hyldnir Frostrider - has been surprisingly good, so I put in a second copy. It almost never combos with Moorabi like I intended, but it's just good tempo and gets stuck in my hand as a dead card surprisingly rarely. (If I have a big board that I don't want to freeze, I'm generally winning anyway.)
  • Mana Tide Totem - this wins and loses games more than any other card in the deck. And when I say loses games, I don't just mean when you don't draw it. I mean when it sticks on board too long and starts milling you. That's happened way more often than I expected. I don't think there's any real alternative in Shaman to playing this, though. Card draw is pretty important.
  • Spirit Echo - sometimes a dead card, sometimes an excellent alternative to card draw. Can get you another White Eyes, importantly. I definitely don't think putting a second copy in is a good idea, but I've been fairly pleased with the card's performance.
  • Stonehill Defender - I actually think it's just as good in Shaman as it is in Paladin. It's a must in this deck, for early tempo as well as for picking up extra copies of crucial taunts such as White Eyes.
  • Tar Creeper - best early game anti-aggro card I can come up with.
  • Avalanche - it's ok. Pretty good to combo with Moorabi if he happens to stick for a turn, but also just ok for removal and stalling. Benefits a lot from cleverness. I remember one game in particular when my opponent was in fatigue with a Northshire Cleric on board, and I had a Healing Totem, and I killed my opponent by Avalanching my own minions. Anyway of course that's not the norm ... this card could go, but usually it manages to be decent.
  • Volcano - insanely useful, added a second copy.
  • Voodoo Hexxer - seldom combos with Moorabi, but is still just a decent card on its own, as long as it doesn't get Potion of Madness'd or anything like that.
  • White Eyes - has won me way more games than my other win conditions. Extremely important card to the build. Has only gotten transformed a couple of disappointing times.
  • Moorabi - I mean, obviously I'm keeping him since the whole deck revolves around him, but how good can he be? Answer is ... highly variable. He definitely has been a dead card some games. And he definitely has won me some wacky, crazy, memorable games by a landslide.
  • Thing from Below - I mean, everyone knows this card is good.
  • The Lich King - it seldom wins games (especially because I'm unlucky with which Death Knight cards it gives me ... almost never Death and Decay, for example), but it usually draws removal excellently and sometimes provides a nice speed bump too. I'd like to keep it, especially since it's one of my only KFT legendaries.

Update 9/15/17

Honestly, the Taunt parts of the deck seem to win me more games than the Freeze parts of the deck. So the whole Freeze Shaman concept may be a bust. It just gets out-valued too hard by Control Warlock, Quest Mage, Jade Druid, and Razakus Priest. What cards can I add to a Shaman deck that will make it do better against these control archetypes?

In the meantime, though, I used this deck as an excuse to learn how to upload game clips. So here, by request, is a video of three games of this deck. They're not particularly brilliant games (no Moorabi use, sadly, and some comically dumb moves by my opponents), but that's ok since there will hopefully be more in the future.

OK, when I try to embed the video, it's giving me "Unfortunately, we don’t recognize that video platform, so we can’t embed it." But it's on YouTube, the most recognizable platform in the world. Anyone want to tell me why this isn't working? In the meantime, I'll put the video in a Comment ...
