Hearthstone: Heroes of Warcraft -
#6 Paladins -
Paladin's main weaknesses are the first few turns. It has multiple viable decks but most of those decks have similar matchups overall and while it has a lot of very powerful pieces, it still has to rely on neutral minions to fill in the gaps. Paladin's strength really shines once it gets to the 4-drop spot, but a very aggro heavy environment makes it much more difficult for Paladin to make it to turn 4 without being significantly behind.
