In my opinion Undead Priest is a must have card to win matches because this card plays an important role in the death team. First advantage of this card is that it just costs 2 mana to play with this card. Purpose of the Undead Priest is to make enemy weaker and he achieves it with his abilities. Undead Priest reduces 1 health of the enemy and makes enemy slower. Apart from making enemy weaker he can also attack with magic which is another advantage of this card. In my opinion if you play with death team then it's a must use card in very battle.
