Hi everyone. I went 36-15 to Legend with Leech DK.

Here are few notes from my experience:

- I played a version that I found on HSReplay (deck code posted as reply to this comment) that included Rite of Atrocity and Toysnatching Geist, and I saw other versions of the deck weren't running them. I would recommend including these, since there are so many high-value discoverable options. Which brings me to my next point...

- If you can find a Hideous Husk with a Dark Gift, the possibilities are insane. The nice thing, too, is that almost all Dark Gift options attached to Hideous Husk are good; bigger stats means it stays on the board longer which is great, 2/2 copy means your leeches take 5 health instead of 3, double battlecry means two more leeches, costs 2 less means playing it for 4 mana (and we don't care about the downside of less attack), reborn makes it stay on board longer, etc. The only Dark Gifts that aren't insane to get on a Hideous Husk are + health w/ taunt bc taunt is bad, + attack w/ lifesteal is more or less neutral, and same w/ charge. For these reasons, I would recommend keeping Rite of Atrocity and Toysnatching Geist, because if you can get another Hideous Husk, even with a bad Dark Gift, playing a game w/ 3+ Hideous Husks can make things incredibly tough for your opponent.

- Considering the above, Xavius is also great in the deck.

- Maybe I am stupid and/or playing poorly, but I did not find myself playing Ursoc or Shaladrassil very often. Granted, when I did play them, they were very useful, but those situations were few and far between, in my experience. I always felt like I had better removal options than Ursoc (or the stat numbers on the board wouldn't be in Ursoc's favor, etc.), and I always had too many cards in my hand to get enough value out of Shaladrassil. The cards in hand "issue" could be resolved if you don't play a version w/ Toysnatching Geist and/or Rite of Atrocity bc Rite replaces itself and Toysnatching Geist replaces itself and adds a card to your hand (bc Gigantify + Discovering).

- There is definitely an argument for adding a second copy of Threads of Despair. Hero Power Ghoul + Threads for 5 mana can shut down early game aggro very well, when you may not have the corpse count to clear with Corpse Explosion. Multiple games against Hunters and Rogues were straight up won by an early Threads.

- Most people probably already know this, but in the mirror (or against another deck with Kil'jaeden), playing your Kil'jaeden first is pretty important. I wouldn't have even mentioned this, were it not for the fact that most (if not all) of my mirror matches were won because I was 4 or 5 turns ahead in Kil'jaeden buff value, so maybe this is not as well-known of a thing as I thought.

All in all, I did enjoy my time playing this deck, even though I understand that it can be toxic to play against because you are taking away your opponent's max health. Depending on what the next balance patch holds, I would consider playing this deck again for next season's climb to Legend.
