Season 4 of Guild Ball is just 9 days away. As Steamforged looks to preview all the cards before it hits its release date, they're showing off entire Guilds all at once. In this instance, it's the Mason's Guild. I, for one, was interested to see what changed, since they're one of the Guilds that I play.
From the post:
In this episode Andrew talks to Bryce about the Season 4 Masons, and how they have changed.
