Merchant (circus troupe)

This merchant is far more interested in playing gwent than actually selling anything. However, he does sell several Gwent Cards, including:
 * Emhyr var Emreis: Invader of the North
 * Foltest: Son of Medell
 * Catapult
 * Dol Blathanna Archer
 * Gaunter O'Dimm: Darkness (2x)
 * Mahakaman Defender

If Geralt beats him at gwent, he also gives the witcher the Schirrú card.
