Hearthpwn

This deck seems to have... outperformed a majority of other decks on launch day.

It's simple, deal damage to yourself, play it like a Zoo'Lock where you just play a bunch of cheap minions then obliterate your opponent with your final The Demon Seed quest reward, Blightborn Tamsin.

Your BEST cards to victory to look out for in mulligan is definitely Darkglare, Backfire and basically any 1-cost minion, preferably powerful ones like Kobold Librarian, Flame Imp and Tour Guide. 

Crystallizer may be the best minion to turbo complete your quest combined with Raise Dead as there is no downside to it. You don't technically lose health, you just convert it into armor plus it can save you later if you need armor if Blightborn Tamsin is active, since it will damage your opponent for 5 and give you 5 armor.

If cheating out Flesh Giant on turn 3/4 wasn't enough, Unlicensed Apothecary is an alternative win condition AFTER you finish your quest. Don't blow yourself up.

Who would've thought Unlicensed Apothecary would actually be useful in a deck, almost 5 years after release?

Good luck grinding to Legend with this one!
