This deck mainly does one thing Circle of Healing to ensure that his Firesworn don't die. Since he has 7 Firesworn, he is paralyzed and you are guaranteed to win, provided that you can deal with his buffs. I personally have played over 100 games with various iterations of this deck, and have never lost a game where I cast Circle of Healing on turn 5.

In the event that he is able to kill off some of his Firesworn, do not concede. Try to keep as many Firesworn alive as possible. If they aren't silenced, do not allow more than 2 to die per turn.  You mainly want to build a board and then kill him quickly before he plays enough minions to break through your taunts and kill your damage dealers. You will find that he often will just refill the board with more firesworn.

If you need to replace a card, pretty much any card but Circle of Healing can be replaced, but you will be able to win less consistently. If you want to know why a specific card is/is not in the deck, feel free to ask in the comments and I will respond as soon as I can.

The deck currently has 2 main win conditions. On the turn where you cast Circle of Healing, if you have the mana for it you can cast Light of the Naaru on one of the Firesworn (or your own face if you've taken enough damage) so that the Firesworn is still damaged, so you get a Lightwarden. Then cast Circle of Healing to get a massive Lightwarden. This will guarantee lethal in 2-3 turns, though this can be shut down by Lava Shock. You can prevent the Lava Shock by using Power Word: Shield on the Lightwarden. The other win condition is the Divine Spirit + Inner Fire combo. Power Word: Shield can also be used for this to maximize damage. The Gurubashi Berserkers can act as a pseudo-win condition, but I've never actually killed my opponents with only berserkers, as usually by that point I have a taunt on board on which I can use Divine Spirit + Inner Fire for lethal a turn or two faster than the berserkers can finish the game.

Useful Tips

• Mulligan for Circle of Healing. While other cards may be important, this one wins you the game.
• Do not use Circle of Healing unless there are Firesworn at 1 hp; you need all of the mass healing that you can get.
• In the case that he draws Bloodlust, your taunts are there to protect you from dying. Each bloodlust does 21 damage, so make sure to stay out of range. He has two copies of bloodlust, so do not think you are safe just because he already cast one copy of bloodlust.
• Immediate draw is more valuable than end of turn draw, so if you have the option to play Loot Hoarder or Novice Engineer, play the loot hoarder. If you have the option to play Coldlight Oracle or Acolyte of Pain, play the acolyte. This way, if you need a specific draw to win/not die, you will have the immediate draw available.
• Let's say that you have lethal next turn as long as he doesn't have Bloodlust. If he has 9 or more cards in hand, you may play Coldlight Oracle. If he has 8 or less cards in hand, you should not play Coldlight Oracle, as it gives him extra chances to draw Bloodlust.
• If you haven't silenced the enemy Firesworn and the Firesworn are at 1 hp and you are going to die if you don't do something about it, Divine Spirit can be used to stop some of them from dying and give you an extra turn or two to draw what you need.
• Keep in mind that silenced Firesworn still count as Firesworn that died that turn for the deathrattles of non-silenced Firesworn.
• You always go first.

Card Replacements

While most cards in the deck are fairly unique, that does not mean that there aren't any good options for replacements. A second Unpowered Steambot can be nice for consistency, and mass dispel is nice for a little bit of extra silence with card draw as an added bonus. Northshire Cleric can also be used but only with utmost caution, as you can easily end up milling 10+ cards if you aren't careful. And other more expensive draw cards like Gnomish Inventor can work as well, I just find them to be a bit clunky for the purposes of this deck, but they can work.
