Mulligans
General Mulligans
against mage mulligan for shadow word death to answer mountain giant
against druid mulligan for mass hysteria, holy nova and forbidden words, it's worth it to use forbidden words on a 2/2
against warlock mulligan the same as druid but also look for shadow word death to answer sea giants
against rogue mulligan for forbidden words and mass hysteria for answers and northshire cleric and injured blademaster to get on board
against hunter, warrior, paladin, priest and shaman there aren't any specific things to answer so just try to curve out and establish board presence.
