Mulligans
General Mulligans
Gives you a board presence on turn 4 and as I said before, almost always gives you value.
Aggro Mulligans
AOE, spot removal and life gain are always nice.Midrange Mulligans
Kill their threats... throw down a Ragnaros or something... you know the drill
Combo Mulligans
The AOEs work well against Grim Patron and Miracle Rogue.
Control Mulligans
Just try to grind it out till Malygos comes.
