Eredin Bréacc Glas: The Treacherous is one of five possible gwent leader cards for the Monsters deck, having been added on with the Hearts of Stone expansion. Tips Unlike most effects which double the strength of cards this one does stack with Commander's Horn. Meaning if you have a Commander's Horn played in the close combat row enemy Spies played on your side will have their strength quadrupled. The effect is most effective against the Nilfgaardian Empire Gwent deck as the spies in that deck have high strength value, less so against Northern Realms Gwent deck but still can be effective. The card is obviously useless against any other decks as they have access to only 1 spy which has 0 strength.
