Hearthpwn

This deck is very powerful when you mulligan and manage resources correctly.

The deck contains many powerful removal spells, and spells to cheat out copies of big minions.

For the mulligan, I like to keep copies of the cheat cards: 

Ancestor's Call , Eureka! , Muckmorpher

And of course Lightning Bloom

Aggressively mulligan for those cards. Generally mulligan away the big minions except  Y'Shaarj, Rage Unbound since that's the most powerful big minion in the deck, and you want to cheat out copies of it. Against aggro it can be alright to keep some removal such as Hagatha's Scheme, and you can keep a Scrapyard Colossus if you have the cards to cheat it out.

Here's a short video of me playing the deck to reach legend, including decision making. 

A counter to this deck is Reno Priest, which is played pretty often. It is very important to hold resources and release it in a burst - you can't play 1 big minion at a time. Save your cards for a good turn where you can summon minions and protect them using Ancestor's Call . 

Against most aggro decks, you are favoured. If you combo Ancestral Spirit onto Scrapyard Colossus, that's 28 health worth of taunts with 7 attack. Most aggro decks don't run silences anymore.  

When overloading using Serpentshrine Portal , keep in mid future turns in case you topdeck an Ancestor's Call , Eureka! or Muckmorpher. I like keeping it in my hand to push for lethal in later turns. 

Here's proof of my winrate. I admit I had a lucky streak, but this deck can definitely consistently hit mid 60s winrate in this elo if played correctly.
