412.1. A static ability may generate a continuous effect or a prevention or replacement effect. These effects last as long as the object with the static ability remains in the appropriate zone.

412.2. Many Auras and Equipment have static abilities that modify the permanent they’re attached to, but those abilities don’t target that permanent. If an Aura or Equipment is moved to a different permanent, the ability stops applying to the original permanent and starts modifying the new one.

412.3. Some static abilities apply while a spell is on the stack. These are often abilities that refer to countering the spell. Also, abilities that say “As an additional cost to play . . . ,” “You may pay [cost] rather than pay [this object]’s mana cost,” and “You may play [this object] without paying its mana cost” work while a spell is on the stack.

412.4. Some static abilities apply while a card is in any zone that you could play it from (usually your hand). These are limited to those that read, “You may play [this card] . . .,” “You can’t play [this card] . . .,” and “Play [this card] only . . . .”

412.5. Unlike spells and other kinds of abilities, static abilities can’t use an object’s last known information for purposes of determining how their effects are applied.
