Mulligans
General Mulligans
In general we need some card draw.
Aggro Mulligans
Vs aggro - survivability
Imo new Banana Buffoon will make Quest mage far mor predictable we have Arcane Artificer Doomsayer Ice Barrier Ghastly Conjurer some cards to survive early, few AOEs (mb replace polymorphs with more). New blastwave works well with quest.





























IMO,
Adding 2 Simulacrum is ineffective having 2 copies of Molten Reflection. Also, Polymorph and Acolyte of Pain reduce your draw potential in comparison with Research Project, not to mention that Banana Buffoon it’s quite a risk when your board it’s empty (most of the time) because you HAVE to use the bananas on an enemy’s minion.
The combo BM Thalnos with Blast Wave could be an option but 7 mana option still dangerous without froze cards rather than Blizzard.
Meteor is good, but excessive to me because you already have Polymorph 15 points of damage, excessive enough maybe the AOE damage? or 6 mana Arcane Artificer but in that case, I would suggest Another Blizzard.
Doomsayer gets vulnerable without Frost Nova, for me the best 5 mana removal, We can use Glyph, but uncertain to be honest.
