Reaction

Reaction is a Permissive keyword that can be present on Spells, Units, Rune Abilities, Legend Abilities and Permanent Abilities.

Reaction grants the corresponding card or effect all abilities and permissions of Action.

On Spells and Units: "This can be played during Closed States on any player's turn."

On Rune, Legend, or Permanent Abilities: "This can be activated during Closed States on any player's turn."

The corresponding card or effect is not restricted to Closed States or Showdowns; this permission is inclusive of all other timings and options available to the ability.

Reaction does not alter the function of any instruction of the Card, Rune, or Effect it is on; it is only Permission.

Whether or not a Game Object, Spell, or Ability has Reaction is a characteristic and may be checked or referenced by other Game Effects.
