Undoubtedly, Yennefer of Vengerberg was a similarly legendary female sorceress. Finding her in a Gwent deck would not be much of a surprise. She was a hero card with seven battle points, even possessing an extra "medic" skill, which allowed the player to choose one card from their discarded pile and play it instantly. This was a reasonably practical skill in Gwent.
With such a precious and rare neutral card, usage was mandatory.
Her quote was as so ---- ---- "Yennefer of Vengerberg, raven-haired, clad in black and white, the first thing you would think of on a December morning."
