Hearthpwn

I like that swap; however, I don't have Leeroy. Typically Doomguard sticks in my hand until it gives me lethal; or until I can play it without discarding anything. Now I don't necessarily agree that it attacks twice as it is often removed fairly quickly (if they have any removal) as most everything else in this deck doesn't require instant removal.

I loved this idea of a deck but was getting wrecked by face/aggro so I added 1 shadowflame and 1 or 2 demonwrath at the cost of a dark iron dwarf, 1 abusive sergeant, and the ironbeak owl. I usually love my silence but I haven't missed them yet. My favorite Knife Juggler combo has to be Knife Juggler into implosion. 

In regards to my changes, I may add an ironbeak at the cost of the shadowflame since I typically am stuck waiting for a power overwhelming (If I don't discover one) before I use it as most of the attack damage is fairly low- 3-4 damage even after a defender of argus/dire wolf alpha buff.

I don't necessarily agree that Keeper is the best of LOE but it's definitely the best for Paladins. I find Dark Peddler very decent (lots of 1 mana Warlock cards are ridiculous) and it actually has board value unlike Jeweled Scarab. Reno is definitely one of the more powerful ones as healing to full late in a close game can be game-winning (often but not always). I really enjoy the Raptor, and enjoyed Murlocs even more since the addition of Anyfin can happen and Everyfin is Awesome. Although the Elise proc makes games fun... it takes a lot of cards/RNG to get the all legendary deck going.

I would say for usefulness of the card, Entomb would HAVE to be in the argument with Keeper as the best of LOE, with Unearthed Raptor coming in third or fourth with Reno in the other remaining position.

Skulker is mainly a card to make up for the poor-ish AOE that rogue has. It's main aoe cards are Fan of Knives, and Blade Flurry, which is largely based on your current weapon dmg. They are very useful against aggro which is plentiful in today's ladder, but asides from that matchup, it's not extremely useful as it's easy to remove (Most 2 mana cards do 3 damage).

Happy feast of Winterveil!   Or Merry Christmas.

I don't agree that it's impossible to complete a deck; however, whatever deck you make, could be better if you had other cards from adventures. You will need to lean on old cards that used to be strong, but were replaced by better cards: For example, Sludge Belcher has replaced Senjin Shieldmaster as a key 4/5 cost taunt. Since you don't have nax, you'd have to use the senjin. 

Otherwise- I'd consider looking at the older pre-adventure decks and then add what you like from the newer expansions to replace older cards (maybe you have a decent amount of TGT/GvG cards). That's just my suggestion.

I would recommend checking out some of the twitch players. I recall seeing that some offered coaching, although I can't remember who off the top of my head. Especially from a well known/professional player whose style you like.

I originally thought Tomb Pillager would be better as 4/5 as well, but think of the purpose of its deathrattle. Do you want the coin or the board presence? This is why I'm betting it was made 4/5 instead of 5/4. It may be easier for someone to remove; however, you're getting the coin back for a still decently statted 4 drop. 

That being said, coins can also be gotten from Cutpurse if they aren't immediately dealt with and I don't feel that it is used much. The coin still makes Dr. Boom a possible play on turn 6 if pillager isn't silenced; however, I don't know how much value you'd get out of using raptor on tomb pillager. 

You do need RNG but it seems like ridiculous luck you need too. I've had several mirror Entity get me stupid minions right before he plays a big one. I've also had my fair share of 3 turn losses due to him getting 3 free 5 or 6 mana minions out even with ideal draws. I feel like more control could be added to this deck; however, it's 90% about getting the armor out since you can't easily out summon him with his free minion/spell each turn. 

This was one of my least favorite brawls. I don't even remember getting a win last time this one was around in week 11. I guess at least it's not Ragnaros versus Nefarian.

I enjoyed the tavern brawl thoroughly, although I do enjoy Dominion where it's not pay to win. 
I end up getting some interesting combos such as Shadow Madness a Dreadsteed and suiciding it into one of his minions so it wouldn't return to his board at the end of the turn. It is very RNG with the discover mechanic but still involves skill in those closer games of choosing the right card that will close out the match.

Machinae is right on the mark. I think it wouldn't make sense being 8 mana because it only has a combined x/x of 8 which is definitely 4 mana range. It wouldn't slow the meta down as it would be hard to get to turn 8 if you're countering rush decks.
