Seems interesting for a card game fan. Runic Lord is a ranged or melee character?
There really isn't any one attack type intended. If ranged fits your image more, use that. Otherwise a sword and shield, or Crows-Beak will do just as handily!
With it being a magical class, how the attack looks in the end is completely up to interpretation. I can see it as being a mage flinging spells from a distance, or even a mage creating magical weapons to use.
