Numia, the Unending Sufferer

If Numia, the Unending Sufferer leaves the field by any means: search your library for another card with "Numia" in it's name and put it into play.
{t}The first Instant or Sorcery you cast this turn may be paid by milling cards from the top of your library equal to the coverted mana cost of the spell. Each player creates a copy of the spell and may select new targets for those copies.
