I play a mage control deck in Hearthstone.
Warriors doing the Sulfuras quest always beat me because they don't mind being controlled. They just have to delay with taunts until they get Sulfuras, then they win.
Is there any way to counter Sulfuras, or should I just concede as soon as I see the quest?

Best Answer
Let me start by stating that the Taunt Warrior usually has the upper hand in control matchups. When finding yourself in unfavorable matchups you usually have to take more risks than you would take in even matchups. Don't be afraid to make all-in plays if you think that there is no other way to win at some point.
Winconditions
To correctly approach a specific matchup you need to identify either side's wincondition. For the Taunt Warrior this is obviously completing the quest and closing the game out with the Ragnaros heropower.
You wincondition is controlling the board and finishing the game with minion attacks. This is actually true for all your matchups, since you have no other tools to win the game.
This already gives you a rough idea of your general gameplan: Aggressively pushing for board control and keeping it by using your powerful AOE-spells until you minions represent lethal damage.
Execution
You absolutely must secure board control in the early game and pressure the Taunt Warrior. Always keep in mind that most of the Taunt Warriors run two Brawls, so make sure to not overextend. However don't tunnelvision on playing around the second brawl, you probably have to take the risk of them having it ready at some point.
In the midgame, focus on maintaining board control by using Blizzard and Flamestrike. The perfect scenario is having a good board by turn 5 and then following this up with Blizzard and Flamestrike in the following turn.

Deck optimization
Your deck has a lot of one-ofs which is not really common outside of Reno decks (RIP). On the one hand this lets you fit more tech-cards but on the other hand this makes your deck very inconsistent.
You definitely should run two copies of:
This adds 6 more cards to your current deck, so I propose to cut:
Other considerations:
Depending on the type of decks you encounter on the ladder, you should merge some of your early game one-ofs into two copies of the same card. This overall makes your deck a lot more consistent and increases the odds of drawing specific cards in the early game.
