Hearthpwn

This deck was inspired by iicescream's deck here.

Strategy:

The Silence and Spellbreaker in the deck should never be used on your dragon; if you do, Lady Deathwhisper's minions will begin to attack and kill your dragon and it is game over.

Use your Silence and Spellbreaker instead against Lady Deathwhisper's taunt minions, which she sometimes resummons. 

Every turn possible, try to attack Lady Deathwhisper's face using Flash Heal, Binding Heal, Circle of Healing (preferably when you have one or more Northshire Cleric on the board for card draw, and don't heal Lady Deathwhisper's taunt minions.

Use your Shadow Word: Pain and Shadow Word: Death to remove her taunt minions or to remove her troublesome minion, Shadow Ascendant. 

Never buff your dragon; if you buff it with Power Word: Shield or through some other method so that its health is above 5, you will have to fully heal it before it can attack Lady Deathwhisper. That is why this deck does not run Power Word: Shield or any other buff for the dragon.

Hold Bloodmage Thalnos to use with Circle of Healing if possible so it will heal for a full 5 and allow your dragon to attack.
