Hearthpwn

This deck has been a lot of fun. Once completing the quest, there are countless ways to double battlecry down your opponent, and there are plenty of removes to ensure you get a chance to do just that. I particularly love that this deck doesn't have many spells off the bat, which makes for amazing opportunities for Lorewalker Cho to annoy the opponent into wasting a removal, which you then get yourself. I'll be writing a full guide soon.

Mulligan:

Keep any 1 or 2 cost minion.

Against aggro, keep Zilliax (also, try to combo with Nightmare Amalgam if possible). Also keep Lightning Breath. There are plenty of dragons to activate this, and it's deadly on turn 3 or 4.

Tips:

If you go second, keep the coin as long a you can. Once you've completed the quest, having 11 mana for Dragonqueen allows 4 dragons at 0 mana, if your hand only has 6 cards or less.

Don't be afraid to drop Zephrys early. There are some really great early cards that can help ensure a win.

Try to save Lifedrinker for when the quest is complete so that you heal for 6, and then another 6 during Shudder. He is a great one to use Bog Slosher or Barista on as well.

I would love any comments / suggestions to make this stronger and more successful. This is my first post, so I'm excited to make this as good as it can be!
