Spell

• 213. Spells
  • 213.1. Every nonland card is a spell while it’s being played (see rule 409, “Playing Spells and Activated Abilities”) and while it’s on the stack. Once it’s played, a card remains a spell until it resolves, is countered, or otherwise leaves the stack. For more information, see rule 401, “Spells on the Stack.”
  • 213.2. A spell’s type, supertype, and subtype are the same as those of its card.
  • 213.3. The term “spell” is used to refer to a card or a copy of a card while it’s on the stack.
  • 213.4. Every spell has a controller. By default, a spell’s controller is the player who played it.
  • 213.5. If an effect changes any characteristics of a spell that becomes a permanent, the effect continues to apply to the permanent when the spell resolves.

Example: If an effect changes a black creature spell to white, the creature is white when it comes into play and remains white for the duration of the effect changing its color.
