How to Get
Frost Presence x 2 are automatically included in all players' collections.

Golden Frost Presence is a reward for raising a Death Knight to a high level.

Frost Presence is soulbound and cannot be crafted or disenchanted.

Strategy
Frost Presence Freezes all characters (minions & heroes), regardless of who owns them, so it's usually smart to play it when you have fewer minions than your opponent, or when your opponent's minions are more dangerous. In and of itself, Frost Presence seems to be a weaker version of Frost Nova, but combined with other powerful Death Knight cards like Frost Strike, Shatter, or Horn of Winter, or with the Death Knight's hero power, Remorseless Winter, it can easily be a game-winning card.

Lore
Frost Presence, in World of Warcraft, is one of three Presences (functioning much like "stances") that Death Knights can maintain. It increases the generation rate of Runic Power by 20%, and decreases the duration of crowd control effects on the Death Knight, making it a powerful Presence for dealing sustained damage.
