Balin, Tremaster [The Hobbit]

Storied (If you control three or more artifacts, legendaries, and/or Sagas, you have an enduring story for the rest of the game.)
Whenever Balin or another Dwarf you control enters, you may discard your hand. Draw X cards, where X is the number of cards discarded this way. If you have an enduring story, Balin deals X damage to each opponent.
