Hearthpwn

This deck is pure cancer.  I replaced Frothing with Corsair for pirate synergy and tempo.  It could use some tweaking to optimize it, but it's already stupid easy to play and basically unbeatable with good draws.

Maybe I've just been having good luck, but this deck seems solid even against pirate warrior.  I just try to ramp and struggle to survive until I stabilize, then go off with lots of Jade Idols.  It feels like the deck needs more taunts, heals or another auctioneer, but it's been able to squeeze out wins with what it has.  Granted I'm only playing in the rank 5-3 range right now.

The deck definitely takes some practice though.  Using Jade Idols, Nourish, and choosing when to play Fandral are not straightforward.  You need to maximize your value to win against aggro.

The original post had 2 force of nature and no Loatheb.  The deck seems pretty light on removal with only one force though.  It's so nice to be able to use one to clear and still have combo.  Can't have everything I guess.

This deck is solid, even in ladder since everyone is playing control and priest right now.  It requires a lot of patience and precisely timed plays, but feels very good against just about every deck.  With Leeroy gone this is actually one of biggest single turn damage decks.  Freeze mage is a problem, but since they get crushed by most other decks right now you'll never see one in ladder.

The only odd choice is Azure Drake instead of Loatheb.  The deck is very light on draws, so I probably just answered my question, but Loatheb is so good for setting up a combo kill (and saving your ass the turn before you kill them with the combo), that I'm very surprised it's missing.  I'm a crap deck builder though so what do I know.

I've had the exact opposite experience at rank 5 (playing casual since I didn't feel like grinding to legend this season).  You need to play this like a late game control/token deck, despite the fact that it looks like the midrange version.  Control the board and survive until you get a massive FoN + Savage Roar turn.  Shade is surprisingly important in this deck and must be played correctly against most classes, or you just lose.  Plus, if you make mistakes like wasting Keeper on the wrong target, not using Savage Roar or FoN for necessary removal, and not utilizing Haunted Creeper's deathrattle to your advantage, you'll lose badly.

Against aggro and zoo, you need to mulligan for cheap minions and removal (and obviously innervate).  It may seem like the deck needs taunts to deal with zoo, but it doesn't.  Kill their minions with your minions and face.  Once you stabilize around turn 6 you can heal with lore next turn and prepare for the combo.  Will you lose if you get a bad draw and they draw on curve?  Yes, but so do most decks.

This deck is a lean mean 1 turn pwning machine, but you need to play it correctly to get it to work.

This is a great deck, and probably the best version of zoo for hitting legend.  The only changes I made are 2x Elven Archer and Leper Gnome for Flame Imp and Argent Squire.  Flame Imp just isn't that good imo.  Against better decks and better players, the imp rarely gets to attack and rarely wastes a worthwhile removal spell or powerful minion.  Leper Gnome always does at least 2 damage, costs no life, and can always be played no matter what turn it is.

Argent Squire is a good minion, but low impact and a potential liability with all the Blood Knights out there.  I like that archer often gives you a minionless method of killing enemy minions.  It works well with Knife Juggler, pops shields for free, combos with Amani Berserker, and in rare cases can finish off a low opponent behind taunts.

I've also considered replacing Amani Berserker with Faerie Dragon, but I think Amani often gets overlooked since it's actually a decent threat and draws removal.  The reason Amani never does any serious damage is because players fear it.  A 5/2 or 5/1 for 2 mana is something that can't be left alone, so it usually gets taken out by wrath, backstab, frost bolt, etc.  But that usually means it drew removal away from your wolf, juggler next turn.  Played smart, and in the right circumstances, Berserker can also be a devastating counter to 1-2 damage AoEs.  I look at Berserker as having the same pressure as Flame Imp, without the drawback if it gets completely countered.

This deck is unquestionably awesome in tournaments.  One of the best players in the world uses it, he goes almost undefeated every time, he's probably the best druid player in the world, and I've seen other pro streamers go on 10+ legend rank winning streaks with it.

However, it seems to have a couple flaws at the lower ranks.  First, it can lose hard to rush decks that get a good start.  This deck only has 3 AoE damage cards, so the odds of not drawing one early are high.  If you don't get an innervate and a big taunt, or if they remove/bypass it, you're screwed.  It also seems to have problems against odd non-meta decks that have ways of bypassing taunts or "bad" control cards that don't see legend rank play.

The second flaw in my opinion is Sylvanas.  Maybe I just suck, or I haven't had a good opportunity to use her yet, but she is a big fat dead card most of the time.  Her mana cost is too high to play most other cards in the same turn, and good players will rarely let you steal something.  She's more of a pseudo threat that usually acts as a weak 5/5 with taunt.  I'm not sure what to replace her with, but I always wish I had something else in my hand.

This deck is great and fun to play.  What it lacks in consistency (relative to hunter, druid, rogue, zoo), it makes up for in big sudden unstoppable wins.  I wouldn't be surprised to see it pop up in tournaments as a 3rd all or nothing last round deck.  Warrior, and to a lesser extent paladin, are not good match ups, but it does surprisingly well against hunter, zoo, and control.  It even does ok against rogue, with most games depending on who has the better hand.

It's actually pretty strong right now since everyone is playing more conservatively.  Once people figure out that dumping your hand and filling the board with minions stomps this deck though, it might be a bit tougher to play.  I'm guessing they think aggro mage has aoe.  Hopefully they keep playing around it.

Switching Dire Wolf Alpha for Explosive Trap can be super clutch at the right moment.  Wolf could end a close game by a couple points, while trap could turn around a certain loss.

Unlikely since Kolento hasn't used one in this deck for a while.  Leeroy is a combo finisher, and this deck doesn't need it.  If you notice, there's not a single card that needs to be held onto for very long.  If you need to hound for early removal or draw, Leeroy becomes a dead inflexible card.  He's bad as removal, since you give your opponent 2 minions that need to be dealt with, and 6 damage for 4 mana from a single source isn't great with this deck.
