Mulligans
OTK deck using the mage quest, arcane giants and alextrasza.
Use frost nova/blizzard + doomsayer, meteor and flamestrike to board clear. Draw into your otk with the many draws in your deck, arcanologist helps to draw defensive secrets against aggro and also thin out your deck so you’re more likely to draw combo pieces. The OTK is double arcane giant + time warp into alextrasza your opponent to 15 and then attack with both arcane giants.
