Protector cards have high health but deal low amounts of damage. They have "Taunt" abilities, which force all currently played opponent cards on the board to attack the Protector card, no matter where they are placed. Use Protector cards to prepare large damage combos or protect your Priest cards. Try to have always have one Protector card in your deck. Also have at least one Priest, as well as one Enchanter to buff your team. The remaining positions should be Mage or Assassin cards, which are the main source of damage.
