  Official Ruling
  The last ability of Jhoira's Familiar doesn't reduce its own cost while you're casting it.

  Official Ruling
  A spell is historic if it has the legendary supertype, the artifact card type, or the Saga enchantment subtype. Having two of those qualities doesn't make a spell more historic than another or provide an additional bonus—a spell either is historic or it isn't.
