Hearthpwn

This deck is based in the deck Guide to heroic Maexxna (basic + white cards)

Basic rules:
-Your aim is to fill the enemy's board with 1 attack minions. You should destroy his 1/2 spiders that deathrattle into smaller spiders in order to do this.
-After he has 7 minions, he can't play more and he can't damage you more than 7 per turn.
-NEVER play more than 2 minions or he'll attack them and free a spot on his board.

I do it in the first try replacing Inner Rage for Antique Healbot.
The Antique Healbot is better than the Earthen Ring Farseer + Voodoo Doctor + Armor Up! combo, because you get +1 hp and use 1 less mana per turn.

Just use a minion with charge to do damage every turn OR
Do this rotation:
a-) In a turn play Antique Healbot + Arathi Weaponsmith (you do 2 damage with the weapon in this turn)
b-) Next turn play Antique Healbot + Kor'kron Elite, Wolfrider or other minion with charge (you do 2 damage + X for the minion with charge).
c-) Repeat step A and B.

TL/TR: Get the Antique Healbot and a minion with charge.
