Mulligans
General Mulligans
Most of the time you just want to keep T1 card in order to play fast
Aggro Mulligans
Against aggro decks, your priority is to take control of a minion to suicide it on another minion
Midrange Mulligans
Against a midrange deck, you have to play faster than your opponent, and try to steal from him some midrange card
Control Mulligans
Against a control deck, you can take your time to play more slowly to express your game
The goal of this deck is to steal card from the opponent. This is a deck more fun than tryhard. The good point of this deck is its RNG that made all games differents.
I made some choices which can looks weird:
-> The quest Awaken the Makers : Even if the deck has not enough Deathrattle cards (5/7), you can copy them with Faceless Manipulator (so 7/7), copy a Deathrattle with Carnivorous Cube, and steal cards from your opponent. Amara, Warden of Hope and Archbishop Benedictus are cool against a Fatigue deck
-> I put Arfus and The Lich King for the Death Knight cards Death Grip and Frostmourne . These two are perfect for the mechanic of the deck xD
