Hearthpwn

So I was looking for some fun priest decks because I own most priest cards. I later found one that I felt was capable of winning with a decent win-rate. I made some slight changes which in my opinion makes the deck a lot better.

The archetype is somewhat of a big priest but instead of swarming the board with huge minions you're building up for an OTK of atleast 40 damage depending on how you play.

Now please do rate the deck if you like it! :) Credits to the original creator of the idea.

Changes made

- The original deck included The Lich King but I replaced it with one Obsidian Statue since I felt like it is more capable of taking care of more minions + the healing is great. Sometimes The Lich King also prevented me of playing Shadowreaper Anduin.

- Removed one Shadow Word: Death since the current meta mostly consists of agro decks and doesn't include that many big minions anyway.

- Added one Mass Dispel for added card draw and a way of dealing with large boards of annoying minions like the ones taunt druids sometimes get.

Playstyle

For the OTK you need atleast one Mind Blast and Vivid Nightmare paired with an upgraded Lesser Diamond Spellstone. For the OTK to work one of each of your minions must to have died (excluding Obsidian Statue since you don't need it for the OTK). Once you have reached 10 mana you can play the Lesser Diamond Spellstone which will summon Radiant Elemental, Malygos and Prophet Velen. Now when your spells are discounted you play your Vivid Nightmare on your Prophet Velen and finaly you can play your Mind Blast dealing 40 damage to your opponent.

For board removal we got Spirit Lash and Holy Nova which you can both pair with Malygos or Prophet Velen. Spirit Lash especially is insane with Malygos because you usually get a full clear and you also heal back to full health even from low health. 

Eternal Servitude is for bringing back your big minions to life so you can effectively combo with your other cards.

Psychic Scream is very good against agro decks and decks with wide boards.

Sometimes you may need to watch out with playing your Obsidian Statue against classes like mage, shaman and sometimes warrior because they tend to place minions on you side of the board which makes your resurrection cards summon copies of those minions.

Muligan

Radiant Elemental is always a keep.

Lesser Diamond Spellstone is almost always a keep unless you feel like you need other cards to counter agro decks.

Shadow Visions is great because you can discover your other important spells.

Shadow Essence is usually a keep and very good to get on turn 6 or turn 5 with the coin. Sometimes you can even with the use of Radiant Elemental coin out the card on turn 4.

Spirit Lash is sometimes good against agro if you already got other good card choices.

Further details

After roughly 100 games the deck performed with a winrate of 62%.

For me the hardest matchups are against agro warlocks and sometimes odd paladins.
