Mulligans
Combo Mulligans
Keep Simulacrum if you also have the ApprenticeKeep Iceblock because you dont have Arcanalogist
Don't keep the 'fuel' of your Auctioneer, you have plenty of them
Another variety of None Quest Exodia Mage
A bunch of cheap spells to get the Gadgetzan Auctioneer rolling (more effective if you combine with one of your EXTRA Sorcerer's Apprentice ). Your only mission is to survive, draw and draw
The extra freeze from Breath of Sindragosa and Freezing Potion help you a lot with aggro.
Hard to use.
Include only minimum number of copies of cards required to complete OTK combo, while, you must keep a lot of hand cards for auctioneer. There is always a risk of your hand cards full and key cards get burned.
And, 2 frost bolt, 2 Doomsayer and 2 frost nova are not sufficient to survive until turn 7~8 when you can start your auctioneer rolling.
