I tried some of Kolento's Demonlock deck this weekend. It's pretty damn powerful, my winrate isn't so great though, maybe 50% or just higher... It's extremely skill intensive. Managing your life and knowing when to tap, how and when to use Defile... etc.
Defile is an amazing card. Paired with Tainted Zealot it's 4 mana for a 5 damage AoE at minimum as long as 1st cast kills something 1 or 2 health.
The Demonlock decks are ranging between 52%-58%.. so many variants right now.

I tried some Jade Druid and went on a crazy losing streak. Either I suck with jade druid or just had some bad luck. Jade Druid still has the highest win rate right now, but I have no idea if that applies at Legend ranks... It could just be Jade Druid has inflated stats right now due to winning against a ton of very greedy decks at the lower ranks.

So a card I've tech'd into my Control Paladin list is Nerubian Unraveler...
I feel like every time I play this card it makes a positive impact on the game, but maybe I'm biased. It works so good in Paladin because you only have a few spells, and most are cheap. Spikeridge is your biggest and you normally just hero power afterwards anyway, which you can still do on 10 mana if Nerubian is down.
I definitely feel like this card alone has won me at least 2 games single handily, maybe more. Of course, I don't draw it every game.
My 2 prime examples have been against Druid:
1.) Aggro Druid uses Living Mana+Mark of the Lotus. Has 2 mana remaining, can Roar next turn. I have a small board, put down Nerubian, shuts off Roar. He has to trade 2 of his dudes into it now. I clear out the rest of his board on my turn using weapon/minions. I go on to win the game in a few more turns.
2.) Jade Druid is down to 1x Ultimate Infestation and 2x Jade Idols. No more cards. He's already used 2x Auctioneer and 1x Ultimate Infestation. I have a board of small things 3-4 attack, his Jades are around 15/15 now. He shuffles both Idols into his deck, planning to Infest & draw 5 at a time. I drop Nerubian, shuts off his Ultimate Infestation. He can now only draw 1 Jade at a time. He concedes.

I also had played it against Priest & Rogue... Won vs Priest, he had a 5 mana Death for it, which means less Death for Tirion/Lich King/Ragnaros, might not have mattered overall though.
Lost vs Rogue.... Rogue played Backstab+Vilespine onto it, which seemed like a great trade to me. I eventually lost to a board full of giants & vancleaf I couldn't clear.

So yea, overall I am liking the card, it sucks up some premium removal and with the insane spell-heavy decks everywhere, I think it is an awesome card right now. All of the Druid decks are spell heavy, and it shuts off Infestation completely, Quest Mage, Servitude/HL priest, Rogue, all have tons of spells.

I'm on a 5 or 6 win streak with Control paladin right now, had to gain back some Legend points after playing shit decks all day. My final match last night was against HL priest, which I figured would be a loss, especially due to the hype around here, but ended up winning pretty easily. The deck is still good, and I've lost to it before (not as Paladin), but it's just so draw dependent.
The key was making him blow his Dragonfire, and then rebuilding a board of 3-4 attack shits, his DK wouldn't kill anything. He probably had DK in hand but never used it because he had to heal himself due to the pressure.
