This is the Aviana-Kun-Malygos combo Druid I used to hit 12 wins in the Wild Brawliseum.  It's identical, card for card, to the deck I used to hit Legend in Wild this season, and I personally find this particular Malygos Druid build to be the most optimal in the current meta.

Unfortunately, the Tavern Brawl closed immediately after I accepted the rewards, so this blurry rewards screenshot is the only one I have.

 There isn't anything particularly groundbreaking about this deck, as many players are currently piloting similar Malygos Druid decks on the Wild ladder.  Nevertheless, there are a few minor differences between my build and other builds, that I would like the discuss.

First, there is an ongoing debate on which combo piece to include: Alexstrasza, Ixlid, Fungal Lord, or a second copy of Faceless Manipulator.  I am a strong proponent of double Faceless, and I believe the Faceless Manipulator to be superior to Ixlid in particular.  All 3 of these, when drawn, can help deal substantial amounts of burst, usually well over lethal.  The decision on which one to include should be based on which card is the most useful outside of the Aviana combo, and I think that Faceless Manipulator is the most versatile by far.

It should be noted that Ixlid doesn't actually deal more damage to matter in most scenarios.  When used in conjunction with the first Faceless, the difference between Ixlid and the second Faceless is that Ixlid puts 4 Malygos on the board, instead of 3.  That may seem significant, but in most cases it doesn't matter.  3 Malygos provides +15 spell damage, which means 2 spells are required to deal 30 damage.  4 Malygos provides +20 spell damage, which is also a 2-spell 30 damage lethal.  The only matchup where the extra +5 spell damage from Ixlid is potentially better is in the Druid mirror due to armor gain, and I find that even then, it's difficult to gain enough armor to go outside of combo range. 

The other difference between my build and the vast majority of other Malygos Druid decks is that I'm running only 1 copy of Ultimate Infestation.  Unlike in other control Druid decks like Jade Druid, Malygos Druid cares a lot about overdraw, as burning a combo piece removes your win condition.  As a result, the second UI is almost never played during a game, and often the first one is eschewed for other sources of card draw.  Ultimate Infestation is obviously extremely powerful if drawn at the right time, so by running only 1, I'm lowering the consistency of drawing UI in favor of removing a dead card in the later stages of the game.  To compensate, I tend to draw more aggressively using Nourish and Branching Paths,

In place of the second UI, I'm including Fandral Staghelm in my deck, as another 4 drop.  Fandral combos well with Wrath, Nourish, and the Death Knight Battlecry and Hero power.  Mostly, though, he provides a 3/5 body and a soft taunt.  This main reason he's in the deck is to improve the consistency of Oaken Summons.  When including only the 2 Ironwood Golems as 4 mana and below minions, usually you will draw one before one of the Oaken Summons.  This reduces the Oaken Summons to essentially 4 mana, gain 6 armor, which is terrible.  By including a third 4-drop, the consistency of Oaken Summons is significantly increased, for the same reason that decks with 2 Mad Scientist often include 3 secrets.

Finally, here are the replays of the 14 games I played with this deck in the Tavern Brawl, in chronological order:

0-0: Win vs. Evolve Shaman

1-0: Win vs. Secret Paladin

2-0: Win vs. Resurrect Priest

3-0: Loss vs. Giants Warlock

3-1: Win vs. Secret Mage

4-1: Win vs. Midrange Paladin

5-1: Win vs. Cubelock

6-1: Loss vs. Tempo Mage

6-2: Win vs. Midrange Hunter (featuring a rather unique lethal at the end)

7-2: Win vs. Murloc Paladin

8-2: Win vs. Secret Mage

9-2: Win vs. Murloc Paladin

10-2: Win vs. Secret Mage

11-2: Win vs. Cubelock (I missed lethal near the end while pondering on how a particular interaction with Mistress of Mixtures worked.  Eventually, I just went for it.)

While I definitely made a few mistakes throughout these games, these replays should provide some overview on how to pilot these decks.
