383.3.aIf a Triggered Ability says “you may”or “they may” as the first part of its Effect, the controller of its source will choose whether or not to perform the Triggered Ability during finalization. Example: Tideturner reads “When you play me, you may choose a unit you control at another location. Move me to its location and it to my original location.” This “you may” appears as the first part of its effect, so the choice represents whether or not to perform the triggered ability.383.3.bIf a Triggered Ability contains a cost within instructions at the beginning of the effect or immediately following the “you may” or “they may” that appears as the first part of the effect, that cost is treated as the base cost of the Triggered Ability. Example: Ekko, Recurrent reads “[Deathknell][>] Recycle me to ready your runes.” In this case, “recycle me to ready your runes” is a cost within instructions that appears at the beginning of the effect of the ability, and thus “recycle me” is taken as the base cost of the triggered ability. Example: Insightful Investigator reads “When you play me, choose an opponent. They reveal their hand. You may pay 2 XP to choose a card from their hand. If you do, they discard that card and draw 1.” The “pay 2 XP” is a cost within instructions, but because it does not appear in the first part of the effect, it is not taken as the base cost of the triggered ability. Paying 2 XP is performed on resolution.383.3.cTriggered Abilities can be put on the Chain during Closed States or Open States on any player's turn.383.3.dIf more than one Triggered Ability is Triggered simultaneously, then the player that controls the Abilities selects the order to place them on the Chain.383.3.eSome Triggered Abilities will trigger “once each turn,” or “N times each turn.”
