Mulligans
This deck is based on surviving the early and midgame until you can get your quest reward and than using to kill your opponent without them interacting. As soon as you have cast at least 10 spells and gotten your quest reward, cast two of your Arcane Giants and then your Time Warp. Pass the turn back to yourself and then cast Alexstraza making your opponent’s health 15 so you can swing with the 16 damage you played last turn. The shell is pretty much a classic Freeze Mage shell with a few new cards to both help survive and achieve the quest.
