The most effective and true pay to play strategy by convincing Geralt to buy all of the cards he can with vendors is the most effective way to get a piece of the readily available Gwent cards. This will launch the quest, but it will also include Geralt's A Miraculous Guide to Gwent, which will show how many cards Geralt is missing in each region of the map. This influx of witcher content has new and returning players alike picking up The Witcher 3 to experience life as a witcher first hand, and it isn't much of a life for Geralt without a healthy dose of Gwent.
With the game coming to PlayStation 5 and Xbox Series X/S before the end of 2021, new and returning fans may want to keep an eye out for all the Gwent cards from the start. Though the world of The Witcher 3 is massive, there are people in nearly every town that one can challenge to a match. Note that if Geralt assists Anisse and Berthold in the Now or Never quest, Olivier at the Kingfisher Inn can be missed. There are three ways to buy Gwent cards: acquiring them from vendors, winning Gwent matches, and giving them as rewards for quests. Players are tasked with finding and obtaining every single Gwent card in the game in the Collect Em All Witcher 3 quest.
Gwent is a fast-paced card game that can be played within The Witcher 3: Wild Hunt on every platform.
