Mardroeme is a special gwent card in the Blood and Wine expansion and part of the Skellige deck.
It is only useful for transforming Young Berserker and Berserker cards.
- The card can be a double-edged sword as when used it prevents the player from using Commander's Horn in the same row.
- It is possible to bypass this flaw by playing Dandelion in the close combat row. While in the ranged combat row by playing Ermion instead of this card. However such solutions rely heavily on luck
- Mardroeme seems to be derived from the Swedish word "Mardröm" which is "Nightmare" in English.
