Hearthpwn

Yeh don't play this deck. I've given it ample opportunity now (with attempting a few small edits), and it just gets trashed when your opponents are 70% shaman. I've gone from rank 6 to 10D, and i've won exactly 3 games total after playing about 20.

Other decks just have too much insane dmg or board presence too fast. This doesn't even come close to being able to deal with it.

High Abbess Alura + Desperate Prayer is a combo that lets you always get Alura's effect to play the shard, rather than relying on Venomous Scorpid

I think the deck needs to double up on anti-meta cards. And Illucia

This deck is pretty terrible in current meta. Things are too fast, and you just can't stall for long enough. I went something like 2-10+ at Diamond 5-10. I did face all warlock and shaman though (+ 1 druid/DH).

You've gone a demon, 2 dragons, a pirate, and elemental, and a few beasts. Maybe you should throw in an N'Zoth as an alternate win condition.

Giving this a spin at D5

What's the reasoning behind having no spells?
