Hello! This is my easy pack OTK Mage for this brawl, pretty straight forward, cycle your cards for cards such as Evolved Kobold, Frostbolt, Ice Lance, Flamewaker, Emperor Thaurissan, a Sorcerer's Apprentice etc, pretty much just all cards you can use for damage and Emperor Thaurissan.

You have Arcane Explosion for bord clear and cards such as Babbling Book and Ethereal Conjurer for extra damage or utility.

When you have a hand full of damaging spells etc just play Emperor Thaurissan and OTK next turn by playing all your cards while using Ice Block to prevent dying.

Keep in mind you dont have to have lethal in hand after Emperor Thaurissan, if you're about to die without Ice Block and haven't dropped Emperor Thaurissan or dont have lethal you can drop a Gadgetzan Auctioneer if you added that and Sorcerer's Apprentice if you have in hand and cycle for lethal.

Replacements:

-1 Novice Engineer
+1 Bloodmage Thalnos

-1 Evolved Kobold
+1 Malygos 

-1 Fireball
+1 Ice Block (So you can drop Emperor Thaurissan 1 turn later with no risk of dying that turn)

-2 Gnomish Inventor
+2 Azure Drake

-2 Loot Hoarder
+2 Gadgetzan Auctioneer

-x Babbling Book or Ethereal Conjurer
+x Frost Nova or Duplicate (Duplicate can be really good for cards such as Flamewaker and Sorcerer's Apprentice

-1 Emperor Thaurissan
+1 Sorcerer's Apprentice Yes. You read it right, you can indeed replace Emperor Thaurissan in this deck as all your minions are 1 mana and you mostly use spells so it will cost some more mana to use the full combo but the spell cost will go down by 1 which is all we need really and replacing this makes the deck very cheap

If you have some other cards i haven't thought of for replacements be sure to let me know in comments, thanks!
