Steamforged is working on bringing you the new Rookie League for Guild Ball. This new format allows players to use a Rookie in their games, then build them up throughout the League, choosing several different options as they go. Steamforged is taking pre-orders for the whole bundle of players, as well as selling them individually.
From the announcement:
After their successful launch at STEAMCON, The rookies are now available for pre-order for the first time with brand new sculpts!
Each model comes with their own set of upgradable rookie cards for use in your casual Guild Ball games or leagues.
They can also be used as Alternative Models for your existing players in tournament play!
