Hardcast
Hardcast (or Paying Retail) is Magic: The Gathering jargon used to describe the playing of a spell by paying its mana cost. It is usually used when a spell has an alternative cost, or a permanent could be put into play by a means other than casting it. For example, playing Force of Will by paying is hardcasting it, while playing it by paying 1 life and exiling (pitching) a blue card is using the alternate cost.

The inability of some decks to hardcast a portion of their spells (Reanimator, Tooth and Nail, Hypergenesis, or decks based on Sneak Attack) may be an exploitable weakness, as the creatures they want to put into play are dead cards without the respective enablers.
