Presence on Cards outside of the Board — Riftbound Rules

Triggered Abilities on cards outside of the Board rely on the Information Level of the zone they are in.

Section 385 — 9 rules

385.1.: Triggered Abilities on cards outside of the Board rely on the Information Level of the zone they are in.
385.2.: Triggered Abilities outside of the Board will self-describe their context. Example: The triggered ability "When you conquer, you may discard 1 to return this from your trash to your hand." triggers while the card it's on is in the trash, and not anywhere else.
386.: Some Replacement Effects, Passive Abilities, and Triggered Abilities will begin with “once each turn,” “N times each turn,” “once on each of your turns,” or “N times on each of your turns.”
386.1.: Such Replacement Effects and Triggered Abilities will only be applied to the specified number of events each turn, or performed the specified number of times each turn. Once they have been performed that many times or been applied to that many events, they cannot trigger or be applied to a later event in the same turn.
386.2.: If such a Triggered Ability says “you may,” or “they may,” as the first part of its effect, or such a Replacement Effect says a player “may” replace the qualifying event, the controller of the ability has the choice of whether or not to perform or apply it.
386.2.a.: For Replacement Effects, when an event the Replacement Effect could apply to occurs, the player who controls the Replacement Effect may choose not to apply it to the event. For Triggered Abilities, during Finalization of the Triggered Ability, the player who controls the Triggered Ability may choose not to perform it.
386.2.b.: If they do not apply the Replacement Effect, it has not been applied this turn. If they do not perform the Triggered Ability, it is removed from the chain. Example: Zilean, Time mage reads “Once each turn, if you would play a token unit while I'm at a battlefield, you may play that token and an additional copy of it instead.” When his controller plays a token, they can choose not to apply the replacement effect to that event. If they do, they can choose to apply it to a later event of a token being played. Example: A player controls a unit that reads in part “Once each turn, when an enemy unit dies, you may banish it.” When an enemy Recruit token dies, the triggered ability goes on the chain. If they choose not to perform the ability on finalization, it is removed from the chain. When a Stalwart Poro dies later in the turn, they can choose to perform it then.
386.3.: For such Passive Abilities, they will be active until they have been applied to the specified number of events, after which point they will become inactive.
386.3.a.: If such a Passive Ability says “you may” or “they may” as the first part of the ability after the “once each turn,” the controller of the source of the Passive Ability chooses whether or not to apply the ability to the event in question. If they do not, the Passive Ability is Ignored during that event. See rule 764. Ignoring Effects for more information.
