That one Gwint Card in White Orchard

Sooo... I know, there are a lot of Gwint Cards that can be missed. I know, that in White Orchard, you can miss Zoltan, BUT! - some internet site told me, it was findable at the first location in Velen (the hanging tree), where I finally found the card. I also bought all of the cards the merchant (the one saved before by Geralt and the other witcher), but the Gwint book still tells me, I am missing a single card in White Orchard... I fcking hate it. - Does anyone know, if I just missed something? :/

Edit: Oh fuck me, it's Gwent... sorry, playing the German version. ^^'
