Gwent Cards (The Witcher 3: Wild Hunt)

Win from merchants (they don’t, not everyone can buy). Win against blacksmiths, broniks and others.

In addition to the answer above. And rare and strong cards are obtained through the branch of quests with the game of gwent, where you play with the strongest players and acquaintances.

Who can tell where to look (from whom to win) the Avallac'h card? And then I’m already tired of the fact that almost every opponent throws it in the game, but I still haven’t been given it.

So far, the strongest opponent is the person in the garden in the royal palace. Gave the Leader of the North - a defender with a buff for catapults. Barely knocked him out after the Velensky quest players. Compared to him, every merchant is a baby in general.
