From the preview:
Wily, strong, intelligent, and disciplined, Ser Brynden Tully the Blackfish commands the most capable of House Stark’s Outriders. His long life in the Riverlands and unique knowledge of its geography allows his light cavalry to scout, flank, and ambush enemy formations with astonishing efficacy. Enemy forces soon learn to watch their backs in the Riverlands, for fear of the Blackfish. The Outriders mount up in July 2017 when A Song of Ice and Fire: Tabletop Miniatures Game comes to Kickstarter.
Miniatures depicted are 3D renders.
