Lore

Rubblebelt stalkers are scouts and skirmishers for the Gruul Clans. They excel at moving over challenging terrain, whether they're picking their way through treacherous ruins or clambering across rooftops. They favor ambush tactics and avoid confrontations with stronger forces, relying on their superior mobility to make their escape.
