Hearthpwn

The idea: This is a control priest with a potential OTK finisher. However it is not designed to require the OTK and is more than capable of winning without it.

The OTK is the same as Penguin OTK, but uses Forbidden Shaping instead as this card actually has value outside the OTK. It also has Silence and Circle of Healing for the second 0-cost card. Both of which also have value outside the OTK.

The other ways this deck can win are value off Barnes, Eternal Servitude and/or Shadow Essence.

Card Breakdown:

The 0-cost spells: These spells can be used for the OTK in control matchups, or for tempo/Lyra in other matches.

Northshire Cleric: Draw and early plays to slow aggro (OK Essence target)

Potion of Madness/Power Word: Shield - cheap anti aggro spells / fuel for Lyra

Bloodmage Thalnos: Spell damage for board clears and draw (OK Essence target)

Radiant Elemental: Early drop, combos with Lyra (OK Essence target)

Shadow Visions: Grab a second copy of a useful spell (usually Dragonfire Potion)

Spirit Lash: Early anti aggro - synergy with spell damage

Tainted Zealot: Early drop, spell damage (survives both symmetric Board clears) (Good Essence Target)

Acolyte of Pain: Early card draw, Spirit Lash synergy (Good Essence target)

Mirage Caller: OTK Combo piece (Poor Essence target)

Shadow Word: Death - removal

Auchenai Soul Priest: Combo with Circle, good with 0-cost Hero Power (OK Essence target)

Barnes: many with many of the same cards as Shadow Essence (Poor Essence target)

Eternal Servitude - Can win games with a great Rez especially after Barnes/Essense

Greater Healing potion - helps with burn decks and after stablizing

Kazakus - Powerful jack of all trades (Poor Essence target)

Priest of the Feast: Anti aggro /anti-burn, good spell/Lyra synergy (OK Essence target)

Devour Mind: Hand refill

Holy Nova: Board Clear, spell damage synergy

Lyra the Sunshard: Powerful win condition (Good Essence target)

Raza the Chained: OTK combo setup, great for anti aggro sustain (Poor Essence target)

Dragonfire Potion: Great Board Clear

Shadow Essence: A spell that can put Prophet Velen, The Lich King or Obsidian Statue Early

Prophet Velen: OTK combo, improves Spirit Lash and Holy Nova in midrange matchups

Shadow Reaper Anduin: Great board clear vs big midrange minions, OTK combo setup

The Lich King: Powerful rez and pull target, great in control matchups

Obsidian Statue: Powerful rez and pull target, great for stabilization
