Laaneth's summon ability allows the player to find a way to counteract the opponent's play by finding a certain card such as a Guard or creature with Drain. Laaneth can also be used to set up a winning strategy like retrieving Unite the Houses, an action or another source of damage. Because of her high cost in Magicka, she is better utilized in decks that are meant to be in the late game and require a way to react to an aggressive opponent.
