 How to get
|Golden Blessed Champion||800||100|
- As with all enchantments, Blessed Champion runs the risk of being wasted if the enemy uses a silence, transformation or destroy effect on the buffed minion. To ensure the minion is able to make use of its increased Attack at least once, use this spell upon a minion that is able to attack immediately. Playing it on an exhausted minion is inviting the opponent to remove it before it can be put to use.
- As a powerful multiplier of a minion's Attack, this can be very effective for finishing the opponent with an unexpected burst of damage, especially from a high Attack minion.
- Players should be mindful of this card's mana cost, and remember that as a stat multiplier, it should be always be played after other Attack-increasing effects.
