Mulligans
General Mulligans
You really want a ton of board flood stuff
Aggro Mulligans
Against aggro you want to agressively control the board and then go face
Control Mulligans
Specifically against conjurer mage you want this combo to deal with giants. But otherwise you can just play like normal
Flood the board with stuff. A direwolf curved into Bees can kill a turn 3 giant, or Bees can be used alongside Cult master for a bit of reload. Otherwise, plays like token druid.
