General Mulligans
We need some cheap cards in early game, including Doomsayers playing versus aggro decks.
Blizzard showed some really good cards for mage. Especially, hard control cards, that are really powerful in late game. The way to win with this deck, is to keep alive till turn 5-6 (Doomsayers are included in this deck), and then you can use some really powerful cards like Spiteful Summoner and Medivh, the Guardian. Also there are elemental synergies, so Frost Lich Jaina is in this deck.
