When the Hunter's Guild came out in Season 2 for Guild Ball, their box set contained a full team. You had your captain, mascot, and four players all in one place. Previous boxes just came with a captain and two players. Well, going forward, Steamforged is looking to make all their guilds have full-team boxes. The Fishermen, Engineers, and Butchers are thus getting new team boxes.
From the announcement:
Are you looking to become a convert of the cogs? To swim with a new school? Or do you just want to run with knives? Then mark your calendars—Friday, June 23 it's open season for new coaches to join the Butchers, Engineers, and Fishermen. Meet their Captains below.Source
