Hearthpwn

First time reaching legend, pretty easily with this deck!

I tried multiple versions of mage, tortollan and burn. Tried multiple rogue decks, both aggro variants and OTK.
Also tried a few priest decks until I settled on this mage deck and climbed rather quickly from somewhere D5-Legend in about 3-4 hours.
This deck is the final version of the deck, which is teched to mainly counter the swarm of stealth/tempo rogues and pure paladins on the ladder.

Ended on a winrate of 81% at 17-4. Some of the losses were just missplays by me early on before I understood how to play the deck. If you're looking for a solid, quick and relatively cheap deck to push from D5 to legend, I highly recommend this one.

Proof of legend:

The deck plays out pretty much as you would expect, don't be afraid to use arcane explotion or missiles to remove 1 stealthed minion. Be a little greedy with polymorphs(and fish for them) from maly vs paladin, but mind your health.

Always stabilize and try to get board control until you feel comfortable pushing for lethal.

Save cram sessions, hard mulligan for lab partners and missiles/primordial studies. Keep Firebrand on coin. Azure Explorer is a godlike card.

Raz frostwhisper not needed, can trade him for another Cobalt spellkin or even tech a polymorph or w/e you need.

Happy grinding! ^_^
