  If you cast a creature card from your graveyard, then Karador leaves the battlefield, then returns to the battlefield, you may cast another creature card from your graveyard that turn.

  To determine the total cost of a spell, start with the mana cost or alternative cost you’re paying, add any cost increases (such as the commander tax), then apply any cost reductions (such as that of Karador). The converted mana cost of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.
