I guess.. there's no card which increases your range.
Are you talking about long ranged weapons like Bows/Arrows or Guns/Bullets? Well, you can increase the range only by a skill. Melee weapons? Nah, they're "short range" for a reason.

EDIT: Okay. Looked on rocards. *shakes head* No card, only the skills for Archers, Rogues and Gunslingers.
