Mulligans
Aggro Mulligans
Aggro stands no chance against this! Look at all this mass removal! and no worries too much about life because 90% of minions deal 1 damage!
Control Mulligans
Against other control you keep Nefarian Sludge Belcher, etc. Any other cards that act as temporary walls until you get going but you want to use Kel Thuzad combo to keep things going.Use Legendaries sparingly and when in need only against Control! Mage Control is the most difficult deck to play against as well as Warrior Control. Whirlwind and arcane explosion are strong in this one!
Warlock Control against minis!! Pretty solid and most important of all fun!
