Mulligans
General Mulligans
Babbling Book - Can give you an useful spell in the early game.
Doomsayer - Great for maintaining Board Control.
Arcanologist - Perfect for pulling out Ice Block.
Raven Familiar - Good for getting those big spells in your hand early.
Tar Creeper - Very useful against most Aggro decks.
Just a general Big Spell Mage. Features Alanna, Medivh, Jaina. I modified some cards by myself, like including Fireball and Water Elemental instead of Meteor and Arcane Tyrant.
I figured these cards would make the deck a little faster to keep up with all the aggro going on lately.
