Hearthpwn

I love this deck! Been playing it for the last week and it's lots of fun. 

Glad you like it. Have you made any changes?

No, playing as is.

If it isn't a secret - what is your win rate? Is it playable on Ladder? I'm asking because I haven't gotten my 2x Altar of Fire in a bundle, and haven't crafted them yet. So, I wasn't able to play the deck so far.

I am playing ranked, but I only have time to play like 4-6 games a day. I don't track my win/loss but altar of fire is a great card.

I think I win 3-4 games for every one I lose. I lost one game solidly to spell mage, but have beat them a bunch too. Most of my losses so far is when I mess up playing the combo pieces (burning the primes by accident, or playing neeru too early by accident).

Usually, I don't play any self burn cards until I have both neeru and envoy in hand, and then I just try and destroy my deck asap.

It feels great burning cthun peices, or legendary cards with the altar. I like saving soul rend for when my deck is already gone,  and I always try and kill envoy the turn I play him,  so my opponent can't silence/ transform him. 

I also have trouble mistaking deaths head cultists with blood shard bristleback, as the art is similar, but both are great. 

"Free admission" maybe ?

Instead of which card(s) would you play it/them? It wouldn't make much sense, since the deck isn't overflowing with Demons. Plus, the draw engine is pretty stable as it is. It could be better, of course, but - currently - I do not see how could it, without losing a lot of HP along the way.

love the idea of running Nightshade Matron and Hand of Guldan to extra draw since you don't have in your list more cards of 6 mana or above (except Tickatus and Taelan Fordring draws him

A bit similar to my list, but I think that Jaraxxus could be an extra win condition now that it's reworked. Maybe you could have that in consideration. Like the deck, let's see how it works on ladder. First day will be a party, everybody testing things :D
