Karador, Ghost Chieftain

You must pay the costs to cast that spell. If it has an alternative cost, you may cast it for that cost instead.

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 mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.

If you cast one creature spell from your graveyard and then have a new Karador come under your control in the same turn, you may cast another creature spell from your graveyard that turn.
