This is the deck i used to get legend this season, pretty solid matchup versus Warrior.
I'm really happy to see this deck has been noticed and commented, i try to reply to everyone
Feel free to ask everything.
Here's the stats from rank 5
Most comments are about legendaries replacement, so here's a miniguide
Made some changes to fit better this meta, more antiaggro, i removed Ragnaros because in this meta everyone is running at least 1 BGH, in this deck there isn't any target
Some changes after TGT launch
Just updated to the deck i'm currently using
MUST HAVE AND REPLACEMENT (OLD)
I will just speak about Legendaries as other cards are simply an autoinclude in most druid decks and without them the deck can't exist (I'm speaking about you Ancient of Lore)
Cenarius: this class legendary is simply amazing. I used it almost always with the two treants. Stats buff possibility is the cerry over the cake. Used on t9 will likely set up a (7+4+4+4+2=21) damage combo next turn. it buys you time, helps stabilize the board and protect your other minions
Loatheb: Saved my ass a lot of times, simply a must and easily accessible. Drop him not in curve but when you have at least 2-3 minions on board to disable AoE removal, or to make cheap single target removal inefficient. Wonderful drop on t8 when you have FoN combo in hand and you are going for Lethal.
SUB: I think everyone will use it, however the most similar replacement it's Troggzor the Earthinator
Sylvanas Windrunner: i haven't used her for a long time, but when i gave her a try i fell in love. Many opponents go crazy when they see her, trading all their board not to give you a minion, such value. Drop her on an empty board only if you have nothing else to do with your mana.
SUB: There are few subs for Sylvanas Windrunner, as her role and utility can't be found in any other minions. Cairne Bloodhoof [RIP] is best one, very sticky and annoying minion, he fits the "spirit" of the deck. Another good sub is Piloted Sky Golem for same reason of Cairne, they fits a similar role. Last you can make a "tech" choice if you are facing lots of druid and/or taunts (Sludge Belcher), The Black Knight. he will help a lot also versus Handlock, one of the worst Matchup of this deck.
Dr. Boom: As you can see from my profile picture i really love this card. I started playing him in my Control Warrior, but in this deck he really shines. Those Boom Bots are a really pain to deal with. For 7 mana you have 9/9 worth of stats and 2-8 random damage, just CRAZY. If they leave bots on board and deal only with Dr. Boom, next turn you have a 20 damage combo. If they deal with them they loose integrity for their board. Best legendary from GvG imho.
SUB: very hard to replace, top priority to craft. Some "good" subs are: Ancient of War, Sneed's Old Shredder or Malorne. You can also try one of Sylvanas Windrunner subs. Or simply another good 7 drop like Troggzor the Earthinator.
Ragnaros the Firelord: very powerful legendary though RNG based. Even if removed instantly you are sure he impacts the board and you gain at least some value from his first big fireball. I used it not so often but when i did he won me the game usually. You can manipulate the board trading minions to help RNG choose the target (:P). The least important legendary for this deck.
SUB: You can use many subs for Rag, as he is a personal choice and not a must, i'll give some possible replacement however. Sneed's Old Shredder, Ancient of War, Malorne, Troggzor the Earthinator, Kel'Thuzad
MULLIGAN and MATCHUPS (Work in progress)
Druid vs Druid is always a coin flip.
If you have The Coin and Wild Growth, use it on T1 only if you have Shade of Naxxramas
You have to play on curve and be as efficient as you can. Use Sludge to bait Black Knight, and let him waste his BGH on Dr.Boom
//More to come, just very little time
