From CD Projekt Red: “Welcome to the Draft update! We know that we’ve been quiet for some time, but worry not, we didn’t forget about the format and we’re planning bigger changes in the near future. With 8.5 we introduced changes to existing packages which allow for better balance. We’ve also added the 12 new cards from the 8.3 update to the roster!”
