2P: Druid is a class with quite good attack & defense abilities in Hearthstone. His hero power shapeshift(+1 Attack this turn. +1 Armor) is a good example. As Druid, you usually have more freedom to choose the effects according to tactical needs, because many of Malfurion Stormrage's spells have two effects. So Druid is a nice choice to cope with various situations and turn the tide.
