Hearthpwn

The idea of this deck is to utilize secrets and emerald spellstone early to fight for board and to close out the late game with Highmane, Seeping Oozeling, and Violet Wurm in the late game.

I haven't needed Emeriss in this deck yet so it easily replaceable with Dire Frenzy.

Card choices:

Cult master - Cult master is a good way to eke out some draw in the mid game. This card synergizes with most of the deck (Wandering monster, Hunting Mastiff, Unleash the Hounds, Emerald Spellstone)

Witchwood piper - Another piece of card draw that works well in the deck. Mid game this card will either pull hunting mastiff or cult master. Enabling draw/board control. In the late game, it draws highmane and oozeling.

Rat Trap  - can be switched out for any other secret but I find that it's an awkward card for the opponent to deal with that gets a lot of value. By the time the opponent plays 3 cards, they usually do not have the mana to deal with a 6/6. This is great since it lets you control the board with a big minion on your turn enabling wing blast. Can also be a great mind game tool since the opponent expects freezing or explosive.

Mulligans:

Like most secret hunter matchups, keep emerald spellstone for the turn 5 tempo play.

Aggro matchups:

Keep candleshot, explosive trap, wing blast, unleash the hounds

Ctonrol matchups:

Keep wandering monster, freezing trap, eaglehorn bow
