This can either be in response to a specific event or during a particular phase or step. Unless otherwise specified, Trigger Effects can be activated during either player’s turn.

==Trigger Effect==A trigger effect is a type of monster effect that activates at a specific time. This can either Effects are [[Spell Speed]] 1 and therefore cannot be in response chained to other effects, except when multiple Trigger Effects want to a specific eventbe activated simultaneously, or during in which case they will form a particular phase or step. Unless otherwise specified, trigger Chain with each other according to the rules for [[Simultaneous Effects|simultaneous effects can be activated during either player’s turn]].

Trigger effects Effects that are activated in response to a specific event, such as a card being destroyed, or a card being added to the hand, are activated in the yellow box of the "[[Spell SpeedFast effect timing]] 1" chart, and therefore cannot must either be chained to other effectsactivated at this point, except when multiple trigger effects want to activate simultaneously, in which case they will form a chain with each other according to the rules for or not at all. Examples include "[[Jurrac Guaiba]]" and "[[Simultaneous Effects|simultaneous effectsNumber 39: Utopia]]".

For optional Trigger effects Effects that activate in response to "when" a specific eventaction occurs, such as a card being destroyedtheir trigger must have been the last thing to happen, or a card being added to else the hand, are activated in the yellow box of the [[fast effect timing]] chart, and must either cannot be activated at this point, or not at all. Examples include "See ''[[Jurrac Guaiba]]" and "[[Number 39: UtopiaIf... You Can VS When... You Can]]"'' for more information.

For optional trigger effects Trigger Effects that activate "when" are not triggered by a specific event, but rather by a particular period of time, such as the [[Standby Phase]], can be activated when the player has the right to perform an action occursand only during an open game state. This means that they can only ever be activated as Chain Link 1. In this regard, their trigger must have been function is more similar to [[Ignition Effect]]s (except that they are activated outside the [[Main Phase]]) as the last thing player can choose at which point during that time to happen, else activate the effect cannot be activated. See Examples include "[[If... You Can VS When... You CanFire King High Avatar Garunix]]" and "[[Scarm, Malebranche of the Burning Abyss]] for more information".

==Damage Step==Trigger effects Effects that are not triggered by a specific event, but rather by activated at a particular period part of timethe [[Damage Step]], such as the effect of "[[Standby PhaseAlly of Justice Catastor]]", can be activated when the player has the right to perform an action. In this regardactivate immediately upon their effect being triggered, their function is more similar to [[Ignition Effect]]s (only they other Trigger Effects that are activated outside the [[Main Phase]]) as the player can choose at which point during that time in response to activate a specific event. Multiple Trigger Effects of this nature will form a Chain in accordance with the effect. Examples include "rules for [[Fire King High Avatar Garunix]]" and "[[Scarm, Malebranche of the Burning AbyssSimultaneous Effects|simultaneous effects]]".

===The Damage Step=== Trigger effects that activate at a particular part of the [[damage step]], such as the effect of "[[Ally of Justice Catastor]]", activate immediately upon their effect being triggered, similar to other trigger effects that activate in response to a specific event. Multiple trigger effects of this nature will form a chain in accordance with the rules for [[Simultaneous Effects|simultaneous effects]]. For whether or not a trigger effect Trigger Effect whose trigger does not exclusively occur during the damage step Damage Step can be activated during the damage stepDamage Step, it is best to consider each card on a case-by-case basis. Usually, if such a Trigger Effect cannot be used at that time, its ''TCG'' text will state "except during the Damage Step," though this is not always the case.

Spell and ===Continuous Trap Cards can ===If a [[Continuous Trap Card]] has an effect that triggers, it is also have effects that trigger. When possible to activate both the effect of an already face-up Spell or Trap Card is triggered, and its effect in the same Chain Link in response to the event that triggers the effect functions just like monster trigger effects and activates in at the time when the yellow box of player has the right to activate a [[fast effect timing]] chart. If multiple effects are triggered, monster or otherwise, the rules for [[Simultaneous Effects|simultaneous effects]] are followed.

If a continuous trap card has an effect Continuous Trap Cards which have effects that triggers, it state they must be activated while the Trap Card is also possible to activate both already face-up on the trap cardfield, and its such as "[[Predaplanet]]", cannot activate that effect, in the same chain link in response to Chain Link as the event that triggers the effect at the time when the player has the right to activate a [[fast effect]]Trap Card itself.

For exampleFurther, if a monster you control is destroyed by battle whilst you control a faceContinuous Trap Cards which have rulings that state that their effect cannot be activated in the same Chain Link as the card itself must have first been activated, and resolved, for an action to be able to trigger their effects.
