Hearthpwn

Managed to get through all nine classes and then beat Warlock again on my second account to get the packs.

1st Warlock run was pretty easy with double Battlecry and Scepter of Summoning... managed to get three copies of C'Thun and quite a few buff cards

Mage was very easy; I got +3 spell damage early on and tons of AOE with a Wax Rager and double deathrattle to finish it off

Priest was a little odd. I got through it on my first run with a weird resurrect deck... 4 Sylvanas and double health + buffed hero power to stall

Hunter was pretty much carried by the Rager and double deathrattles. Captured Flag really helped on the last three bosses

Rogue was easily the most difficult. It took a few hours and multiple losses on the 6th boss due to poor card quality. I ended up beating Xol with a heavy deathrattle deck (first time I've ever seen success with Roll the Bones). I was planning on going for mill and took double battlecry early on, but I managed to get through with a completely useless passive.

Druid was half EZ big EZ and half Jade with double battlecry and the Scepter. In most games Kun+Tyrantus was enough to win. Multiple copies of Cenarius destroyed most bosses.

Paladin also included the Scepter. 2 copies of Val'anyr and multiple copies of Boom and Ragnaros and Tarim.

Shaman was power double deathrattles and a bunch of Overload synergy. I pretty much only won because of luck.

2nd Warlock was once again carried by the Scepter, but this time I focused on Giants. The cards that got cut off are 1x Lord Jaraxxus, 1x Voidlord, 5x Molten Giant, and 2x Mountain Giant

I went against Vustrasz and summoned 3 free Moltens on turn 3. It couldn't catch up after that and I won on turn 6.

I honestly can't remember what I did with Warrior. It was the first class I attempted and I didn't save all of my decks.

Of getting Vustrasz the Ancient as your final boss and having this happen...

Turns out Wax Rager is pretty good with Totem of the Dead and Captured Flag
