Mulligans
General Mulligans
All good cards they speak for themselves and they all have upside.
Aggro Mulligans
Make them kill your guys or else you heal 4-5 per turn.
To Note:
The game is probably going to be decided before turn 10 so don't be afraid to confuse a board full of 2/1s.
Midrange Mulligans
Just all the good value cards that will help gain board control.
To Note:
Confuse is yet again surprisingly good getting their belchers and other sticky minions.
